Calculate the pH of the acetate buffer CH3COOH + CH3COONa, containing 0.01 of each of the compound. Ka= 1.8×10^-5
Answers: 1
![\begin{array}{rcl}\text{pH} & = & \text{pK}_{\text{a}} + \log \left(\dfrac{[\text{A}^{-}]}{\text{[HA]}}\right )\\\\& = &4.74 +\log \left(\dfrac{0.01}{0.01}\right )\\\\& = & 4.74 + \log1.0 \\& = & 4.74 +0.0\\& = &4.7 \\\end{array}\\\text{The pH is $\large \boxed{\textbf{4.7}}$}](/tpl/images/0693/9328/22ba3.png)
