QUESTION 3 The acid-base indicator that was used in the titration experiment is called Hydrochloric Acid. 1) True 2) False 

QUESTION 4 The aim of the Titration Process is to find out the concentration of the unknown solution (the HCl in our experiment). 1)True 2) False

 QUESTION 5 Neutral Solutions: 1)Water is an example 2)Have pH value of 7 3)solutions that are not acidic nor basic 4)All of the above 

QUESTION 6 Suppose 0.22 L of 0.5 mol/L NaOH solution was titrated with 5 L of HCl using phenolphthalein indicator. Calculate the amount of the base and the acid that were used to reach the neutralization point. 1)0.11 mol of the base and 0.55 mol of the acid 2)0.11 mol of the base and 0.11 mol of the acid 3)0.55 mol of the base and 0.11 mol of the acid 4)0.55 mol of the base and 0.55 mol of the acid 

QUESTION 7 A 0.05 L solution of 0.5 mol/L NaOH was titrated until neutralized into a 0.025 L sample of HCl. What was the concentration of the HCl? 1) 0.025 mol/L 2) 20 mol/L 3) 10 mol/L 4) 1 mol/L 

QUESTION 8 50 L of 2.0 mol/L Hydrochloric acid is titrated with sodium hydroxide to form water and sodium chloride. How many moles of sodium hydroxide are consumed in this reaction? 1) 100 mol 2) 25 mol 3) 2 mol 4)0.04 mol 

QUESTION 9 100 L of 5 mol/L NaOH are required to fully titrate a 50 L solution of HCl. What is the initial concentration of the acid? 1) 20 mol/L 2) 10 mol/L 3) 500 mol/L 4) 250 mol/L QUESTION 10 You have 5 mL of vinegar in a flask and 2 drops of phenolphthalein indicator. You titrate exactly 36.9 mL of 0.1 mol/L NaOH from a burette directly into the flask which gives you a pale pink color. This means the solution has reached neutralization. Calculate C of the vinegar in mol/L. 1) 0.02 mol/L 2) 7.38 mol/L 3) 20 mol/L 4) 0.738 mol/L
