The [ OH ⁻ ] in a solution is 1 10⁻¹² ~mol dm ⁻³ . What is the concentration of H ⁺ ions?
Options
- A0.1 ~mol dm ⁻¹
- B1.0 ~mol dm ⁻¹
- C2.0 ~mol dm ⁻¹
- D0.01 ~mol dm ⁻¹
Correct answer
D. 0.01 ~mol dm ⁻¹
Step-by-step solution
In an aqueous solution aligned & [ H ⁺ ] [ OH ⁻ ]=10⁻¹⁴ & [ H ⁺ ]= 10⁻¹⁴ [ OH ⁻ ] & = 10⁻¹⁴ 1 10⁻¹² =10⁻² or 0.01 ~mol dm ⁻³ aligned
