pH of soft drink is 3.6. Calculate the concentration of hydrogen ions in it.
Options
- A2.51 10⁻⁴ M
- B2.3 10⁻³ M
- C2.0 10⁻³ M
- D2.81 10⁻⁴ M
Correct answer
A. 2.51 10⁻⁴ M
Step-by-step solution
aligned & pH =- ₁₀ [ H ⁺ ] & [ H ⁺ ]=10^ - pH & =10^ -3.6 & =10^ -4+0.4 (10^ 0.4 =2.51 ) & =10^ 0.4 10⁻⁴ & [ H ⁺ ]=2.51 10⁻⁴ M aligned
