A solution is prepared at 25 °C that is initially 050 Min chi r acetic acid HCH2CCO2 a weak acid with ra-13x 10, and 0 15 Min pota chloroacetate (KCH,CICo). Calculate the pht of the solution. Round your answer to 2 decimal places. CICO2), a weak acd with K 1.3x 10-3 and 0.15 Min potassium

Solution

pH = pKa + log [salt of weak acid / weak acid ]

pKa = - log (1.3*10^-3) => 2.89

pH = 2.89 + log (0.15/0.50)

pH = 2.36
