Answer to Question #76330 in Organic Chemistry for jessica

Question

A solution of citric acid a trip toxic acid is firearms with a sodium hydroxide solution. A 20.00 mL sample of the citric a is solution requires 17.03 mL of a 2.025M solution of NaOH to reach the equivalence point. What is the molarity of the acid solution?

Answer 1

Molarity of citric acid = M1
Volume of citric acid (V1) = 20.00ml
Molarity of NaOH(M2)= 2.025M
Volume of NaOH (V2)= 17.03 ml
M1V1=M2V2
M1=M2V2/V1
M1=2.025×17.03/20
M1= 1.724 M
