Question

L. A student performing an esn rteo buret readings 073 mt and the Rnalbedga NaOH soution wih na m wh 2. in an acid and base titration when a student filling the buret with NaOH solution, an ai was left in the burette. This air bubble was released d error result in an erroneously the titration. Would this technical molarity of NaOH solution ? calculate High b. Low c. Does not affect the results 3. After completing an acid and base titration, droplets of the NaOH found clinging inner wall of the buret. would this technical error result in an erroneously- calculated molarity of NaOH solution? a. High Low Does not affect the results. c. When standardizing a NaOH solution, 30.37 ml of the solution were required to neutralizs of KHP. Calculate the number of moles of NaOH required to neutralize the KHP. (Molecul weight of KHP 204.2g and Molecular weight of NaOH 39.997 ) 4. Show All the steps of calculations. 2.93 204.3

Explanation / Answer

Answer:-

KHP + NaOH -----------> NaKP + H2O

Mass of KHP = 2.39 g

Mole of KHP in 2.39 g = 2.39 / 204.2

= 0.0117 mol

So, moles of KHP = moles of NaOH

So, moles of NaOH required = 0.0117 mol
