i need help with these three questions
Incorrect Question 2 0/1.25 pts 0.678 g of KHP is used to standardize a NaOH solution. If it took 31.55 mL of NaOH to neutralize the KHP, what is the concentration of the NaOH solution? The molar mass of KHP is 204.22 g/mol. KHP + NaOH --> NaKP + H2O Give the answer to 3 sig figs and use units of M 0.0214 Unanswered Question 3 0/1.25 pts A 25.00 mL HCl sample...

Pre-laboratory Assignment Name: Read the experiment and answer the following questions as directed by your instructor. 1. In this experiment, you will use potassium hydrogen phthalate (abbreviation KHP, formula HKCH.0) to standardize (to determine the concentration precisely of) the NaOH solution. What is the molar mass of KHP? 2. In Part 1, you will titrate a weighed mass of KHP (dissolved in water) with the unknown NaOH solution. What data must you collect in order to find [NaOH)? List the...

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...

PRE LAB : Volumetric Titrations. (Acid-Base Titrations) Name: ID Date 1. How many mL of a 0.103M NaOH solution are required to neutralize 10.00mL of a 0.198M HCI solution? 2. what is the difference between end point and equivalence point? 3. A titration is performed and 20.70 mL of 0.500M KOH is required to reach the end point when titrated against 15.00 mL of H2SO4 of unknown concentration. Write the chemical equation and solve for the molarity of the acid....

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...
