NEET Chemistry pH & Buffer Solutions Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) pH of a neutral solution (i) 7 (b) pH of a strong acid (ii) < 7 (c) pH of a strong base (iii) > 7 (d) pH of a buffer solution (iv) Equal to pK a when concentrations are equal
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
In pure water at 25 °C, the pH is 7, indicating neutrality. Strong acids have pH values less than 7, while strong bases have pH values greater than 7. For buffer solutions, if the concentrations of the acid and its conjugate base are equal, the pH equals the pK a.
