Therefore, 800ml of a 1.25m aqueous ammonia solution contains 1000moles of ammonia.
What is aqueous ammonia solution?
Ammonium hydroxide appears as an aqueous solution with no color. Ammonia concentrations might reach as high as 30%. The eyes become irritated by the solution's ammonia fumes. Ammonium hydroxide is created when ammonia is dissolved in water. A solution of ammonia in water is referred to as ammonia solution, ammonia water, ammonium hydroxide, aqua ammonia, aqueous ammonia, or ammonia. The symbols for it are NH3 and NH4.
How do you make aqueous ammonia solution and why it is used for?
Making an Aqueous Ammonia Solution: Ammonia is dissolved in water to create an aqueous solution. Ammonia dissolves in water at a relatively rapid pace, making water back suction a possibility. Rubber tubing is used to link a funnel to the delivery tube's exterior end in order to prevent this.
Ammonia produced by industry is used as fertilizer in agriculture to the tune of 80%. In addition to these uses, ammonia is made into plastics, explosives, textiles, pesticides, dyes, and other chemicals. Additionally, it is used to clean water sources.
Briefing:
Concentration (C) = number of moles (n) / volume (v)
number of moles (n) = concentration × volume
Concentration = 1.25M
Volume =800 L = 800dm³
n = 1.25 × 800
n = 1000 moles
There are 1000 moles of ammonia in the solution.
