A Level Chemistry Revision: Inorganic Chemistry – Reactions Of Ions In Aqueous Solution

Many inorganic metallic compounds take the form of ions when dissolved in water (i.e. an aqueous solution). The laws that govern their reactions are similar to how compounds react, but with one important emphasis on the role of water in the reactions. In fact, their balanced equations involve water in a generalised stoichiometry form that can be written as:…

A Level Chemistry Revision: Inorganic Chemistry – Transition Metals

The transition metals, or transition elements, are those belonging to groups 3 to 12 in the periodic table, with the exception of the lanthanides and actinides, which have their own periodicity properties. Unlike other elements, the transition metals have more complex behaviours in terms of their electron configurations, and are relatively more difficult to figure out. Many electron configurations are straightforward…

A Level Chemistry Revision: Inorganic Chemistry – Properties Of Period 3 Elements & Their Oxides

Period 3 elements are those in the third row of the periodic table. The way period 3 elements form oxides, and how they react with other chemicals, is related to their positions in the periodic table. Furthermore, you can compare the relative atomic radius, ionisation energy, and electron affinity of the eight period 3 elements. The period 3 elements…

A Level Chemistry Revision: Inorganic Chemistry – Group 7(17), The Halogens

The halogens are the six nonmetallic, highly reactive elements under Group VIIa (column 17) of the periodic table. They’re very strong oxidising agents, which means they take electrons from other substances. They’re also very reactive and usually form salts with Group 1a, i.e. the alkali metals. The name halogen literally means salt-producing. Halogens in elemental form do not exist…

A Level Chemistry Revision: Inorganic Chemistry – Group 2, The Alkaline Earth Metals

Alkaline earth metals, which are under Group 2 (the second column) of the periodic table, are highly reactive metals, though they’re not as reactive as the alkali metals. Their high reactivity is the main reason they aren’t found in a pure or elemental form in nature. Structurally speaking, these metals have two valence electrons in their outermost energy level. Many…

A Level Chemistry Revision: Inorganic Chemistry – Periodicity

Many elements were discovered long before the periodicity of elements was established by Dmitri Mendeleev in 1869. Mendeleev arranged the then-known elements in tabular form and discerned a pattern. With this, he was able to predict the existence of elements that had not yet been discovered. Since ancient times, philosophers have speculated about the fundamental compositions of all substances that…

A Level Chemistry Revision: Physical Chemistry – Acids And Bases

Acids and bases are fundamental in the study of chemistry. The reactions between the two are fast and exothermic, meaning they release heat, which makes them measurable and observable. Even without precise instruments, you can easily estimate whether a reaction has reached its saturation point. Acids and bases are polar opposites of each other, but also complementary. Therefore, their reactions…

A Level Chemistry Revision: Physical Chemistry – Electrode Potentials And Electrochemical Cells

One of the most important applications of chemistry is storing electrical energy for prolonged periods of time. Modern technological products like laptops, mobile phones, solar power, and hybrid cars would not have been possible without the invention of batteries, which are basically electrochemical storage devices that have two electrodes and an electrolyte. In order for batteries to work, regardless of…

A Level Chemistry Revision: Physical Chemistry – Equilibrium Constant Kp For Homogeneous Systems

Analysing the chemical reactions of gases in homogeneous systems may seem daunting at first. Unlike a liquid solution, the volume of gas isn’t constant, so determining the concentration of specific gas reactants is difficult when you base it on volume. This is where the concepts related to the equilibrium constant Kp for homogeneous systems of gases come into play. However,…

A level chemistry revision: physical chemistry - rate equations

A Level Chemistry Revision: Physical Chemistry – Rate Equations

Determining the rate of chemical reactions can be done using rate equations, no matter what type of chemical reaction is taking place. Rate equations are crucial diagnostic tools that are used to analyse the efficiency of chemical reactions. For example, rate equations can be used by chemical manufacturing companies who need their processes to be as efficient as possible so…

A Level Chemistry Revision - Thermodynamics

A Level Chemistry Revision: Physical Chemistry – Thermodynamics

Thermodynamics is the study of how energy, particularly heat, dissipates in a system, and how the mass of substances flows as they’re converted from one form to another. In chemistry, thermodynamics is focused on how energy is transferred and transformed during chemical reactions. Studying thermodynamics allows A level chemistry students to understand how energy flows in a system. Your revision…

A Level Chemistry Revision: Physical Chemistry – Energetics

A Level Chemistry Revision: Physical Chemistry – Energetics

If you’re revising energetics for your upcoming chemistry A level exam, it’s important to reinforce your knowledge of physics and maths. You’ll encounter a lot of questions in your A level chemistry exam that will require you to compute the energy involved in chemical reactions, so understanding the right units of measurement, conversions, constants, and equation manipulations is crucial. Equally…

A Level Chemistry Revision: Physical Chemistry – Bonding

A Level Chemistry Revision: Physical Chemistry – Bonding

Chemical reactions are about breaking and making bonds between atoms, which changes the way atoms share electrons. Bonds can be ionic, covalent, polar, or metallic. Bonding determines the molecular structure and physical properties of a substance. Chemical bonding is determined by various factors, like the number of valence electrons and the ionisation energy. When you’re revising for A level chemistry…

A Level Chemistry Revision: Physical Chemistry – Chemical Equilibria, Le Chatelier’s Principle & Kc

Chemical equilibrium is achieved when the rate of the forward reaction is equal to the rate of the backward reaction. In other words, it’s the state of a system where the concentration of the reactants and products are constant, i.e. they do not change with time. All dynamic systems, including chemical systems, tend to settle at certain equilibrium points under…
