Which of the following sentences is true for a basic solution?
Options
- AFor basic solution, [ H ₃ O ^+] = [ OH ^-]
- BIn basic solution, the excess of OH ^- ions are present.
- CIn the basic solution, there is excess of H ₃ O ^+ ions.
- DThe pOH of a basic solution can be calculated by pOH = - [ H ^+]
Correct 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.
