Expert Solution
Analysis
Given : concentration of benzoic acid = 0.088M.
Ka value = 6.5 ×10^-5
To find : PH of resultant solution.
Solution : As we know that, the ka value of any reaction depends upon the concentration of the reactants and concentration of the products and also it depends upon the coefficients of reactants and products.
Since we know that, pH of a solution depends upon the final acidic concentration of the substance.
PH = - log(H+)
