1gm of HCI and 1gm NaOH are dissolved together in one litre solution of water. The resulting solution is:?​

A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.

As we know that,

no. of moles=

Mol. wt.

Wt.

Mol. wt. of NaOH=40g

Wt. of NaOH=2g(Given)

Therefore,

No. of mles =

40

2

=0.05 mol

As we know that molarity of a solution is defined as the no. of moles of solute present in 1L of solution.

Since 0.05 mole of NaOH are pesent in 1L of of solution.

Therefore,

Molarity of solution (M)=0.05

⇒[OH

−

]=0.05

As we know that,

pOH=−log[OH

−

]

⇒pOH=−log(5×10

−2

)

⇒pOH=1.3

Therefore,

pH+pOH=1

⇒pH=14−pOH=14−1.3=12.7

Hence pH of the solution is 12.7.
