NEET2006ChemistryIonic EquilibriumActual
Given pH of a solution A is 3 and it is mixed with another solution B having pH 2 . If both mixed, then resultant pH of the solution will be :
Options
- A3.2
- B1.9
- C3.4
- D3.5
Correct answer
B. 1.9
Step-by-step solution
aligned & pH of A=3 pH of B=2 & [ H ⁺ ]=10⁻³ M , [ H ⁺ ]=10⁻² M & Total [ H ⁺ ] & =10⁻³+10⁻²=10⁻³+10 10⁻³ & =11 10⁻³ & pH =- ₁₀ [ H ⁺ ]=- (11 10⁻³ ) & =3- 11 & =3-1.04=1.96 & aligned
