NEET Chemistry pH & Buffer Solutions Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) pH of pure water | (i) 2 |
| (b) pH of 10–2 M HCl | (ii) 7 |
| (c) pH of 10–4 M NaOH | (iii) 10 |
| (d) Buffer solution from sodium acetate and acetic acid | (iv) stable pH |
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
Correct Answer
Detailed Explanation
The pH of pure water is 7, the pH of a 10–2 M HCl solution is 2, the pH of a 10–4 M NaOH solution is 10, and buffer solutions maintain a stable pH. This aligns with the definitions and calculations presented in the NCERT content.
