Stoichiometry At room temperature, the product [H⁺] [OH⁻] in a solution is 10⁻¹⁴ moles/litre. If, [OH⁻] = 10⁻⁶ moles/litre, then the pH of the solution will be 10 8 6 12 10 8 6 12 ANSWER DOWNLOAD EXAMIANS APP
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 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 The strong base and strong acid reacts completely ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Two solutions A₁ and A₂ have pH value of 2 and 6 respectively.
