1.	A buffer solution of pH=4 is to be prepared, using CH3COOH and CH3COONa. The concentration of acetic acid and sodium acetate are 110 M and x M. How much will the pH be if 1.5 L of H2O is added to above buffer ? Ka(CH3COOH)=4.7447
Answer» A buffer solution of $p H = 4$ is to be prepared, using $C H_{3} C O O H$ and $C H_{3} C O O N a .$ The concentration of acetic acid and sodium acetate are $\frac{1}{10} M$ and $x M$ . How much will the $p H$ be if $1.5 L$ of $H_{2} O$ is added to above buffer ? $K_{a} (C H_{3} C O O H) = 4.7447$
