Answer 1

Answer:

• 1. 100ml added to 100ml of 0.02 M KCL. 2.100 ml added to 100 ml of 0.02 M HCL =0.02 MH^+

Explanation:

so New morality of HCL new volume =200ml millimoles of HCL =0.02× 100=2 millimoles morality =2millimoles / 200 ml = 0.01 millimoles therefore 0.01 M HCL gives 0.01 MH^+ now solution there will change in Ph Ph decreases so KCN +water --- K+ + OH + HCN Hydrolysis of salt bring ^- OH in solution that increases Ph so the option is 3rd option
