This video explains the unit of concentration of solution known as Normality with examples. You will also learn how to calculate equivalent mass, number of gram equivalent of a solute.
Problems explains:
1) 15 g of H2SO4 is dissolved in water to make 1250 ml of solution. What is the Normality of the solution?
2) 50 ml of 0.2N HCL, 50 ml of 0.1N H2SO4, and 100 ml of 0.2N HNO3 are mixed. What is the Normality of the resulting solution?
3) What is the Normality of 1M solution of H3PO4?
4) A 5 molar solution of H2SO4 is diluted from 1 litre to 10 litres. What is the normality of the solution.
5) NaClO reacts with H2SO3 as
NaClO + H2SO3 ----------- NaCl + H2SO4
A solution of NaCLO used in the above reaction contained 15g of NaClO per litre. What is the normality of the solution?
6) What will be the normality of solution containing 4.9 g H3PO4 dissolved in 500 ml water?
7) 4.0g of NaOH is dissolved in 100cc of solution. What is the normality of the solution?

while the process is right, your solution to the first problem is wrong. It is 0.245 N not 0.229 N

Good Catch, you are right thanks for pointing it out. I like that you solve it by yourself too. I might have entered wrong number in while calculating. Thanks for visiting my channel. Please share and subscribe to support educational videos.

Your solution to Q2 is wrong conversion of ml to litre

@DRMath 3 месяца назад

Thanks for visiting my channel. I appreciate you pointing out any correction, but I am sure it is correct because 1 litre =1000ml so 1ml =1/1000 litre and this is the conversion I used. I am not sure which part you are saying is wring.
