Which of the following solutions has the lowers pH value?
(a) 0.1 molar NaCl solution
(b) 0.01 molar NaHCO3 solution
(c) 0.001 molar Na2 CO3 solution
(d) 0.01 molar NaOH solution
Experts please answer my question and explain the answer as well. Thanks :)
Dear student
its pH is =7.
Rest of the solutions are basic in nature, hence have more than 7 pH.

Option A is correct as NaCl is neutral whereas all other solutions are basic and thus have pH greater than 7.
NaCl is a neutral salt formed as a result of neutralization reaction between NaOH and HCl.its pH is =7.
Rest of the solutions are basic in nature, hence have more than 7 pH.
