Question

How do I calculate my normality?

Community Answer

You can use the formula N= weight of substance in grams*1000/ equivalent weight of substance*volume required in mL.

Question

How do I prepare a 2N HCl solution?

Community Answer

Weigh 7.29g of HCl in a 100ml volumetric flask. Add deionized water to 100ml and shake for a 2N HCl solution.

Question

3.65 g of HCl is present in 100mL solution. What is its normality?

Community Answer

It's 1N, 1 molecular weight in grams per 1 liter (1000 mL) solution. Molecular weight of HCl is 1 (H) + 35.5 (Cl) = 36.5.

Question

How can I prepare 0.02N H2SO4?

Community Answer

You prepare a 0.01 molarity solution of sulphuric acid. It itself will be a 0.02N H2SO4 solution because normality=molarity*(no of H+ ions it can provide)---(for an acid). H2SO4 has 2H+ ions, so you will get the desired solution.

Question

What are the steps to calculate the normality of NaCl?

Community Answer

The equivalent weight of NaCl is the same as the molecular weight which is 40. For example, to prepare a 1N NaCl solution you need to dissolve 40g of NaCl in 1000mL of water. You can also use the formula Normality= weight of substance in Grams* 1000/ equivalent weight*volume required in mL.

Question

How would I prepare 10 N of concentrated H2SO4 (25 ml) whose molecular weight is 98.07?

Community Answer

First, find the equivalent weight. Use this formula: mol. weight / basicity (or n factor), giving you 49.03. Then, find normality using the weight of solute x 1000 / equivalent weight x volume of solution in ml, which would ultimately give you 12.26 grams. Therefore, you have to use 12.26 g of H2SO4 to prepare your 10 N concentrated H2SO4 solution.

Question

How do I add .5 ml of a .5 N solution of HCL when my HCL is .1 N?

Community Answer

You cannot -- your stock solution is 0.1N when you require a solution of 0.5N. You can always decrease the concentration of your stock, but you cannot increase it.

Question

How do I calculate the normality of 10% of NaOH solution?

Community Answer

10% NaOH means 10g of NaOH in 100 ml. Normality=molality.number of protons used molality=mass/RAM x volume(L) =10g/(40x0.1) =2.5M therefore normality=2.5Mx1 =2.5N

Question

When 3.56 g hcl is present in 500ml of solution, what will be its normality?

Community Answer

It should be as follows: H = 1.008, Cl = 35.45, 1 M 36.45, V=1, e.w = 36.45 / 1 =36.45, N = 3.56 G Hal/ 36.45 X 1 = 0.098.
