Question

100 ml of a sample water on titration with N/50 H2SO4 required 6.8 ml of the acid to
Phenolphthalein end point and 13.6 ml of the acid to Methyl orange end point. Determine
the type and amount of alkalinity present in the water sample

Answer 1

Answer:

Total alkalinity is measured by collecting a water sample, and measuring the amount of acid needed to bring the sample to a pH of 4.2. At this pH all the alkaline compounds in the sample are "used up." The result is reported as milligrams per liter (mg/l) of calcium carbonate. and pH less than 5.0.

Answer 2

Concept Introduction: Titration is a method done to mix some acids and bases.

Explanation:

We have been Given: 100 ml of a sample water on titration with N/50 H2SO4 required 6.8 ml of the acid to

Phenolphthalein end point and 13.6 ml of the acid to Methyl orange end point.

We have to Find: Determine

the type and amount of alkalinity present in the water sample.

100 ml of a sample water on titration with N/50 H2SO4 required 6.8 ml of the acid to

Phenolphthalein end point and 13.6 ml of the acid to Methyl orange end point. Determine

the type and amount of alkalinity present in the water sample

Final Answer: 100 ml of a sample water on titration with N/50 H2SO4 required 6.8 ml of the acid to

100 ml of a sample water on titration with N/50 H2SO4 required 6.8 ml of the acid to Phenolphthalein end point and 13.6 ml of the acid to Methyl orange end point. Determine
