Chemistry

A beaker with 1.10×10^2 mL of an acetic acid buffer with a pH of5.000 is sitting on a benchtop. The total molarity of acid andconjugate base in this buffer is 0.100 mol L−1. A student adds 7.00mL of a 0.490 mol L−1 HCl solution to the beaker. How much will thepH change? The pKa of acetic acid is 4.760.

Please show where all numbers comes from.

pH of buffer solution is calculated by using Hendersonsequation pH pKa log conjugate base acid pH pKa log CH3COO CH3COOH Substituting pH 5000 and pKa 4760 we get 5000 4760 log CH3COO CH3COOH log CH3COO CH3COOH 5000 4760log CH3COO CH3COOH 0240Taking anti log on both sides    See Answer
