ITRATIO

Q1

A

titration

experiment

was

performed

with

a

solution

of

HCl

and

another

solution

of

NaOH.

The

aim

of

the

experiment

was

to

calculate

the

concentration

of

the

HCl

solution.

The

concentration

of

NaOH

solution

was

given

to

be

0.1

solution

was

added

to

a
