Answer 2

Answer:

The nature of the chemicals used in laboratories is either basic, acidic or neutral. This characteristic depends on the ions they release. A chemical is said to be acidic if it releases H+ ions in its aqueous solutions. A chemical is said to be basic if it releases OH– ions in its aqueous solutions. In this experiment, we will learn how to find the pH of acids and bases.

Aim:

To determine the pH of the given samples using pH paper or universal indicator. The samples whose pH has to be determined are-

Dilute CH3COOH

Dilute NaOH

Salt NaCl

Dilute NaHCO3

Water

Lemon juice

Materials required:

Six test tubes

Test tube stand

Dilute acid CH3COOH

Dilute base NaOH

Salt NaCl (preparation: dissolve 1 gram salt in 10 mL distilled water)

Water

Lemon juice

Dilute NaHCO3

Glass rod

Measuring cylinder (10 mL)

Standard pH colour chart

pH paper

Glass rod

Dropper

Universal indicator
