a.) In 2-3 sentences, describe how propanoic acid (C2H5COOH) and propanoate anion (C2H5COO-) can be used to make a buffer solution if the Ka of propanoic acid is 1.34 x 10-5. b.) Determine the pH if the concentration of propanoic acid was 1.3 x 10-3 M and the concentration of propanoate was 1.8 x 10-2 M. Is this pH in the range of the buffer? c.) Explain if the pH of the solution in part (b) is in the range of the buffer?

    aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Hence, it's pH changes very little. Due to the presence of both. they are in equilibrium

    @abb0t A buffer is a solution designed to keep the pH from changing, correct?
