A basic solution has a pH of approximately:
pH of a solution X is 13 and pH of another solution Y is 9. Then choose the correct statement:
Statement 1: Solution X is more basic than solution Y.
Statement 2: Solution Y is more basic than solution X.
Statement 3: Solution Y has more OH− ion concentration than solution X.
Statement 4: Solution X has more OH− ion concentration than solution Y.
Statement 5: Solution Y has more H+ ion concentration than solution X.
Statement 6: Solution X has more H+ ion concentration than solution Y.
