Finding concentration from ka

WebSo the Ka is equal to the concentration of the hydronium ion. And since there's a coefficient of one, that's the concentration of hydronium ion raised to the first power, times the concentration of the acetate anion also raised to the first power, divided by the concentration of acidic acid raised to the first power. WebSince the acid and the base are in a 1:1 ratio at the equivalence point, the amount of moles of the acid is also 3.385 × 10 − 3 m o l. We can use this value to calculate the concentration of the acid: C = n V = 3.385 × 10 − 3 m o l 10.00 m L = 0.3385 mol / L View the full answer Step 2/4 Step 3/4 Step 4/4 Final answer Transcribed image text: 2.
