Question 14

What is the pH at the equivalence point when 25.0 mL of a 0.300  solution of acetic acid (CH3COOH) is titrated with 0.100  NaOH to its end point?


Expert Answer

Step 1

The reaction between acetic acid and sodium hydroxide is,

Step 2

From the above reaction, 1 mole of acetic acid is react with 1 mole of sodium hydroxide.

Therefore, mole of acetic acid = sodium hydroxide.

Mole of acetic acid is 0.0075, which is calculated by below,

Step 3

After the neutralization the formed acetate ion is rea...
