o explain how the result of a titration is affected if you titrate past the end point, calculate the percentage error for one drop past the end point of a 30 mL titration, using a 0.100M NaOH titrant. (Note: The volume of 20 drops is equal to 1 mL.) Select one:a. % error=0.1%;b. % error=0.3%;c. % error=0.2%;d. All options are incorrect;e. % error=0.4%;

a) In a NaOH and HCl titration lab: Suppose you add 40 ml of water instead of the 45 mL. How will this affect the calculations for the molarity of the HCI? (In this case, the molarity of HCl turned out to be 0.559 mol/L). While being specific. Explain why it will not matter or it will make the molarity high or it will make the molarity low. b) if you disregard the instructions to titrate until a persistent blue endpoint is reached and instead conclude the titration at the initial appearance of blue, describe the impact on the reported molarity of the CoC12 solution. Provide specific details and specify whether the reported molarity will be higher, lower, or remain unaffected.
