  • Quantitative chemistry The sum of atomic mass (Ar) values in a molecule is the molecular mass (Mr) Avogadro's constant gives the number of particles in one mole of a substance: Number of particles = Avogadro's constant x number of moles One mole of a substance has a mass (in grams) equal to the Ar or Mr. Mole = mass x Mr The percentage composition of a particular element in a molecule can be calculated by dividing the Ar of the element by the total Mr of the molecule. The empirical formula is ...

  • SALTS All solid salts consist of positive and negative ions, and some of them contain water molecules as well. The water in a lattice is called water of crystallisation. One mole of a hydrated salt always has a certain number of moles of water of crystallisation shown in the formula. For example, hydrated copper sulphate (CuSO4.5H2O) has five moles of water for each mole of the salt. GROUP 1 Group 1 elements are alkali metals. They are metals that are usually stored under oil or argon to stop t...

In order to work, ions must be free to move so need to be dissolved in water or melted Electrolyte The liquid that conducts electricity How does electrolysis work There is a flow of electrons that are taken away from the positive electrode and given to other ions at the negative electrode. As ions gain or lose electrons they become atoms/molecules and are then released. Positively charged ions move to negative el...
