Why does ammonium hydroxide give a pungent odor?
ammonium hydroxide is formed by dissolving ammonia in water . ammmonia is formed by decomposition of most nitrogenous organic material ,so it gives a pungent odour
Which ion makes ammonia solution alkaline?
Ammonia react with water molecules. By that OH- are made
What are acids and bases according to Arrhenius?
According to Arrhenius, acids produce a proton in aqueous solution, and bases produce a hydroxide ion in aqueous solution. Hydrochloric acid is an Arrhenius acid because it gives up its proton as it dissolves in water. Sodium hydroxide is an Arrhenius base because it gives up its hydroxide as it dissolves in water.
Why aqueous solution of borax is alkaline?
When borax is dissolved in water it ionizes and hydrolysis of borate ion gives OH (the hydroxyl ion) and boric acid. Since boric acid is a weak acid AND Na-OH is strong a alkali an aqueous solution of borax is alkaline in nature.
What is the yellow powder that gives a pungent smell when left open in air?
sulphur powder
How do you identify zinc cholride?
Add sulphuric acid to salt pungent smell of HCl and white fumes with Ammonia confirm the presence of chloride, in aqueous solution of salt add H2S the black precipitate are formed, in clear solution the addition of small quantity of NaOH gives white ppts. which become soluble in excess, it is the confirmation of Zinc.
Why does ammonium hydroxide give a pungent odor?
ammonium hydroxide is formed by dissolving ammonia in water . ammmonia is formed by decomposition of most nitrogenous organic material ,so it gives a pungent odour
What gives an aqueous solution of an acid the properties of an acid?
An acid gives its properties to an aqueous solution by making free its (acidical) H+ ions (protons) and donating this to the solvent molecules: water, so H3O+ is formed.
Which ion makes ammonia solution alkaline?
Ammonia react with water molecules. By that OH- are made
Cesium why blue in alkali?
Caesium metal is gives a bright blue solution when dissolved in liquid ammonia. The dissolving is believed to cause the production of caesium ions and a free electron. a similar blue colr is produced by sodium, potassium and rubidium. In aqueous alkali solutions caesium ion is colorless and therefore unless the anion is colored the solution is colorless.
What will be form in combining acetic acid and water what kind of solution is it?
It will be an aqueous acetic acid solution. normally water is added in order to decrease the concentration of an acid & gives the diluted form of it.
What are acids and bases according to Arrhenius?

Hydrochloric acid is an Arrhenius acid because it gives up its proton as it dissolves in water. Sodium hydroxide is an Arrhenius base because it gives up its hydroxide as it dissolves in water.
How does an ammonia molecule becomes an ammonium ion?
When you make solution of ammonia. Following reaction occurs-NH(3) + H(2)O NH(4)(+) + OH(-).Hence water gives an H(+) ion to ammonia to form ammonium ion.
When a solution of an acid reacts with a solution of a base hydronium ions react with hydroxide ions to form...?
Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule. Hydroxide ion, OH-, gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water. Combining H3O+ + OH- makes 2 H2O. In other words, an acid and a base combine to neutralize each other as water.
Why aqueous solution of borax is alkaline?
When borax is dissolved in water it ionizes and hydrolysis of borate ion gives OH (the hydroxyl ion) and boric acid. Since boric acid is a weak acid AND Na-OH is strong a alkali an aqueous solution of borax is alkaline in nature.
What is the yellow powder that gives a pungent smell when left open in air?
sulphur powder
Which anions give a white precipitate with silver nitrate?
chloride and sulphate ions give white precipitate with silver ion in aqueous solution but sulphate gives slightly dirty white.
