Question

100 ml of 0.2 M HCI solution is mixed with 900 ml of 0.1 MHC solution. The molarity of resultant solution is​

Answer 1

Answer:

NaOH+HCl→NaCl+H

2

O

1 mole 1 mole

Moles of HCl in 100ml of 1M HCl

⇒

100

100×1

=0.1 mole of HCl

Mole of NaOH in 900ml of 0.1M NaOH

⇒

1000

900

×0.1=0.09 mole NaOH

On mixing 0.09 mole of NaOH will be neutralised

=0.1−0.09

=0.01 mole of HCl in 1000ml solution

Hence molarity of
