We make a basic solution by mixing 50. ml of 0.10 m naoh and 50. ml of 0.10 m ca(oh)2. it requires 250 ml of an hcl solution to neutralize this basic solution. what is the molarity of the hcl solution?
1. 0.015 m2. 0.043 m3. 0.0037 m4. 0.040 m5. 0.060 m

The correct answer is Option 5.

Explanation:

where,

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

are the n-factor, molarity and volume of the

We are given:

Putting all the values in above equation, we get:

where,

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

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

We are given:

Putting values in above equation, we get:

Hence, the correct answer is Option 5.
