How do you prepare 2N ammonium hydroxide solution from 25 percent ammonium solution?
Reference: the density of 25% NH4OH solution = 0.907g/cm³
Therefore 1 litre of solution has mass 907g
25% = 25/100*907 = 226.75g NH3 in 1 litre solution
Molar mass NH3 = 17.031 g/mol
226.75g = 226.75/17.031 = 13.31N solution
To make 1 litre of 2N solution: ( Work in ml= 1000ml)
N1V1 = N2V2
13.31*V1 = 2*1000
V1 = 2000/13.31
V1 = 150.2ml
Measure out 150.2ml of the 25% solution and dilute to 1 litre. This is a 2N solution.

How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
How prepare 6N ammonium hydroxide?
To prepare a 6N solution of ammonium hydroxide, you would first need to calculate the molarity of the concentrated ammonium hydroxide solution you have on hand. Typically, concentrated ammonium hydroxide solutions are around 28-30% NH3 by weight. To make a 6N solution, you would dilute the concentrated solution with the appropriate amount of water to achieve a final concentration of 6N. It is crucial to handle concentrated ammonium hydroxide with care as it is a corrosive substance and can cause burns upon contact with skin or eyes.
