(a) A solution has a pH of 7. Explain how you would :
(i) increase ist pH; (ii) decrease its pH;
(b) If a solution changes the colour of litmus from red to blue, what can you say about its pH?
(c) What can you say about the pH of a solution, that liberates carbon dioxide from sodium carbonate ?
Solution A has a PH of 12,solution B has a PH of 2 and solution C has PH of 6 which solution 1}is a strong acid 2}will liberate ammonia from ammonium sulphate on heating
