CRINSE in water and titrated with NaOH sohution to a phenolphthalein end point. The titration reaction is shown in Eqaation 9 3. A stodent standardized a NaH solution using HCJO, Three HC HD, samples were dissolved E4 9) Masses of H CH,0, and NaDH solution volumes required for titration are recceded in the table on the next page. Do the following caleulations for each titration, and enter your answers in this table a calculate the number of equivalents of HCHO. titrated. 21 Calculate the number of equivalents of NaOfH required for the sitration Caiculate the voluste, in liters,of NaOH solution required for the titraticen 0 Cakulate the normality of the NaDH solution

Explanation / Answer

Question 1

According to the equation One equivalent of acid is needed.

Question 2

According to the equation two equivalent of base (NaOH) is needed. SInce acid has two carboxylic acid groups, 2 equivalent of base needed to neutralize the acid.

Quesiton 3 & Question 4

To calculate the molarity of NaOH, volume of acid and strength of acid should be provided. But here those values are not given. If u have the values mention in comment box.
