MHT CET Chemistry Question (2026) — Solution
Options
- A. For basic solution, [ H _3 O ^+] = [ OH ^-]
- B. In basic solution, the excess of OH ^- ions are present.
- C. In the basic solution, there is excess of H _3 O ^+ ions.
- D. The pOH of a basic solution can be calculated by pOH = - [ H ^+]
Answer
B. In basic solution, the excess of OH ^- ions are present.
Step-by-step solution
In a neutral solution, [ H _3 O ^+] = [ OH ^-]. In an acidic solution, [ H _3 O ^+] > [ OH ^-], meaning there is an excess of H _3 O ^+ ions. In a basic solution, [ OH ^-] > [ H _3 O ^+], meaning there is an excess of OH ^- ions. The pOH of any solution is defined as pOH = - [ OH ^-]. Thus, the only true statement is that in a basic solution, an excess of OH ^- ions are present. Answer: In basic solution, the excess of OH ^- ions are present.
