Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts completely The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse Only OH⁻ and H⁺ ions react in every case ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Colligative properties of a dilute solution are those, which depend entirely upon the Constitution of the solute Number of solute molecules contained in a given volume of the solvent None of these Chemical composition of the solute Constitution of the solute Number of solute molecules contained in a given volume of the solvent None of these Chemical composition of the solute ANSWER DOWNLOAD EXAMIANS APP
