If 20.60 ml of 0.0100 m aqueous hcl is required to titrate 30.00 ml of an aqueous solution of naoh to the equivalence point, what is the molarity of the naoh solution?

Answer : The molarity of the NaOH solution is, 0.00687 M.

Explanation :

The balanced chemical reaction will be:

Using neutralization method :

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

Putting values in above equation, we get:

Hence, the molarity of the NaOH solution is, 0.00687 M.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
