What is the concentration of OH ⁻ ion in a solution containing 0.05 M H ⁺ ions?
Options
- A2.5 10⁻¹³ M
- B5.0 10⁻² M
- C2.0 10⁻¹³ M
- D4.2 10⁻¹² M
Correct answer
C. 2.0 10⁻¹³ M
Step-by-step solution
array ll & K _ w = [ H ₃ O ⁺ ] [ OH ⁻ ] & 10⁻¹⁴=0.05 [ OH ⁻ ] & [ OH ⁻ ]= 10⁻¹⁴ 0.05 & [ OH ⁻ ]=2.0 10⁻¹³ M array
