Question

explain acid-base neutralization reaction and how it occurs?

Write balanced chemical reactions (molecular, total ionic, and net ionic) for the following chemical reactions:

a) Calcium Hydroxide(aq) and Hydroiodic acid(aq).

b) Lithium Hydroxide(aq) and Nitric acid(aq).

c) Barium Hydroxide(aq) and Sulfuric acid(aq).

  A titration is performed between sodium hydroxide and KHP (204.2 g/mol) to standardize the base solution. You place 50.00 mg of solid KHP (Potassium hydrogen Phthalate HKC8H4O4 ) in a flask with a little water and a few drops of an indicator. At the beginning of the titration, the burette reading of the base solution is 43.87 mL and its final burette reading is 10.55 mL . What is the concentration of the base? (explain in details please)

Answer 1

Acid - base neutralization reaction are those where an acid reacts with a base resulting into formation of salt and water.

The main reaction that occurs is:

H+ + OH- = H2O

The source of H+ is acid and that of OH- is base.

The titration of KHP vs NaOH is used for stardization of NaOH. The above said titration cannot be performed because the amount of water added in KHP is not specified due to which you cannot calculate the normality of KHP. And thus standardization of NaOH cannot be performed.
