For an aqueous solution formed by mixing 4.50mL of 0.15M LİOH with 25.0mL of 0.100M C2H5CO2H (propanoic acid), a) determine whether this forms a buffer solution. b) determine the pH of this combined solution. c) state whether the addition of 6.75mL of 0.100M HCI to the solution will have a large or small effect on the pH of the solution. Explain your reasoning (using 1-2 sentences).
