Answer:
46. 2 moles of NaOH
Explanation:
Balanced chemical equation between sodium hydroxide and sulfuric acid
2NaOH + H2SO4 = Na2SO4 + 2H2O
I mole of sulphuric acid is neutralized by = 2 moles of NaOH
23.1 mole of sulphuric acid is neutralized by = 2 x 23.1
= 46. 2 moles of NaOH
Titration experiments require the use of a burette. It is a long graduated glass tube held in place by a clamp stand. It has a tap fixture on the end that regulates the delivery of small volumes of liquid into a beaker in the titration process. Bunsen burners are used to heat substances and crucibles are used to hold items to be heated to high temperatures.
