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, before...
Ammonium hydroxide is a basic or alkaline solution of ammonia which has several applications, such as cleaning windows, treating water, producing alkyl amine, and processing food. It also has some use in the laboratory for qualitative inorganic analysis, and can be used as a chemical indicator.Ammonium hydroxide is otherwise known as ammonia solution, ammonia water, ammonia liquor, or aqua ammonia....
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 that...
Sodium chloride (NaCl), more popularly known as table salt, is one of the most common and important minerals on earth with culinary, commercial, and industrial value. This ionic compound is also essential to life. Many biological organisms would be unable to function properly without sodium chloride as an electrolyte component of cells, tissues, and systems.Sodium chloride is also crucial to...
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 in...
Methylene chloride can dissolve organic compounds, making it very useful as an industrial solvent for many industrial processes. In the food industry, for example, it’s used in the process of extracting caffeine from coffee beans. It’s also used in processing the extracts from hops and other flavourings.Various industrial processes are dependent on methylene chloride as a reagent or solvent. These...
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 certain...
Methylene chloride, otherwise known as dichloromethane or DCM, is an organochlorine compound. It’s a colourless substance that can be distinguished by its chloroform-like smell. While it isn’t miscible with water, it can dissolve many polar organic compounds, making it an excellent solvent. Because of this, it’s well-suited to several industrial applications, such as pharmaceutical manufacturing, paint stripping, paint remover manufacturing,...
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 important...
