A 39.3 mL solution of 0.853 mol/L H(CO)OH is titrated using 0.669 mol/L NaOH. What volume of NaOH (in mL) is needed to reach the equivalence point in this experiment?

A. 22.43 mL
B. 37.60 mL
C. 47.18 mL
D. 58.76 mL

Answer :

Final answer:

The volume of NaOH needed to reach the equivalence point in the titration of the given H(CO)OH solution is 50.1 mL. It's calculated by first determining the moles of H(CO)OH and then using the molarity of NaOH to find the required volume. The answer choices given do not include this result. So , the correct option is c) 47.18 mL


Explanation:

To determine the volume of NaOH needed to reach the equivalence point in the titration of a 3 mL solution of 853 mol/L HOH, we use the concept of molarity and The reaction between HOH and NaOH is a neutralization reaction, and the stoichiometry of the reaction is 1:1, which means one mole of acid reacts with one mole of

First, we calculate the moles of HOH:

Moles of HOH = Volume imes Molarity (mol/ = 0393 imes 853 = 0335

Since the stoichiometry of the reaction is 1:1, the number of moles of NaOH required will be equal to the number of moles of H

Thus, Moles of NaOH = 0335

Now, we find the volume of NaOH solution needed using its molarity:

Volume of NaOH = Moles of NaOH / Molarity of NaOH = 0335 / 669 = 0501 L, which is 1

However, the provided do not include 1 The student should double-check the calculations or consult the instructor for possible errors in the question or the answer choices
