Calculate the pH of solution prepared by mixing 40 ml of 0.1 Macetic acid with 40 ml of 0.1 M sodiumacetate, Given K_a = 10 ^(-5)

Calculate the pH of solution prepared by mixing 40 ml of 0.1 Macetic a

1.	Calculate the pH of solution prepared by mixing 40 ml of 0.1 Macetic acid with 40 ml of 0.1 M sodiumacetate, Given K_a = 10 ^(-5)
Answer» SOLUTION :` CH_3 COOH + CH_3COONa `= buffer ` PH =pKa + LOG ""(S)/(A)= pKa = 5`
