ser-zykov [4K]

Answer:

pH=4.77

Explanation:

From the question we are told that:

pKa for Acetic Acid pK_a= 4.77

Therefore

For Equal Concentration of acetic acid and acetatic ion

CH_3COOH=CH_3COO^-

Generally the Henderson's equation for pH value is mathematically given by

pH=pK_a+log\frac{base}{acid}

pH=4.77+log\frac{CH_3COO^-}{CH_3COOH}

pH=4.77+log1

pH=4.77
