CHML 201 Post lab 20 Answer the Q.'s on a separate sheet of paper and attach to your lab report. Write your name on the sheet. 1. A 0.2736 g sample of sulfamic acid (H2NSO3H) required 15.55 mL of a NaOH solution for titration to the phenolphthalein end point. What is the molarity of the NaOH solution? H2NSO3H(aq) + NaOH(aq) = H2NSO3Na(aq) + H2O(l) 2. A 0.1136 g sample of sodium carbonate required 10.55 mL of a H2SO4 solution for...
3. A potassium hydroxide solution was standardized against the solid acid, oxalic acid dihydrate. The volume of the potassium hydroxide solution required to neutralize 0.317 grams of oxalic acid dihydrate was 48.82 milliliters. Calculate the molarity of potassium hydroxide solution. 4. The molarity of phosphoric acid in a popular cola is to be determined. A 355 mL sample of the cola is O 103 M potassium hydroxide solution. Calculate the molarity of phosphoric acid in the cola.
In an acid-base titration, 22.13 mL of an NaOH solution arc needed to neutralize 24.65 mL of a 0.1094 M HCl solution. To find the molarity of the NaOH solution, we can use the following procedure: First note the value of M_H+ in the HCl solution. ________ M Find M_OH^- in the NaOH solution. (Use Eq. 3.) ________ M Obtain M_NaOH from M_OH^-. ________ M In an acid-base titration, 22.13 mL of an NaOH solution arc needed to neutralize 24.65...
Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
I'm doing a titration lab tomorrow and I am not sure what the formulas are to calculate the moles of NaOH, the moles of HCl, and the molarity of HCl. The objective of this laboratory is to determine the molarity of a hydrochloric acid solution using a known concentration of sodium hydroxide as the titrant. volume of HCl in flask: 25.00 mL the net ionic equation for the reaction is: H+(aq) + OH-(aq) --> H2O(l) I don't have the data...
