Hello, would be grateful if someone could help me with this question.12.50 cm3 of a solution of hydrochloric acid (HCl) of concentration 0.20 mol dm−3 is poured into a beaker. 9.00 cm3 of a solution of the strong alkali calcium hydroxide (Ca(OH)2) of concentration 0.20 mol dm−3 is added. Calculate pH, so far I calculated the moles of acid and OH but as it is a 2:1 ratio, unsure of what to do next?
