In a buffer solution containing equal concentration of B ⁻ and HB , the K _ b for B ⁻ is 10⁻¹⁰ . The pH of buffer solution is

Step-by-step solution

Key Idea (i) For basic buffer pOH = pK _ b + [salt ] [ base ] (ii) pH + pOH =14 Given, K _ b =1 10⁻¹⁰ , [salt] = [base] aligned pOH & =- K _ b + [ salt ] [ base ] pOH & =- (1 10⁻¹⁰ )+ 1 & =10 pH + pOH & =14 pH & =14-10=4 aligned
