A solution is made by mixing exactly 500 mL of 0.149 M NaOH with exactly 500 mL of 0.100 M CH3COOH. Calculate the equilibrium concentration of the species below. Ka of CH3COOH is 1.8 X 10-5

[H+], [OH-], [CH3COOH], [Na+], [CH3COO-} enter answer in scientific notation.

Solutions

Expert Solution

[H+] = Kw  / [OH-] = 1.0E-14 / 0.0245 = 4.08E-13 M

[ Na+ ] = 0.0245 + 0.0500 = 0.075 M

[CH3COOH] = 0 M

[CH3COO- ] = 0.05 mol / 1.0 L = 0.0500 M
