Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
What salt gives a white precipitate when treated with barium chloride?
Nothing - barium chloride is soluble. You can however precipitate either the barium (e.g. with sodium sulphate, giving barium sulpate, or the chloride, e.g. with silver nitrate giving silver chloride precipitate.
What is an atom that gives up electrons?
A cation
Is lithium a cation or anion?
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
Will precipitate dissolve in water?
A precipitate is the name for a solid which has formed from a solution - either through a reaction which gives an insoluble product, or by cooling of a saturated solution.
Is ammonium hydroxide an akali or an acid?
Ammonium hydroxide is an alkali because it gives OH- ions in water and gives a salt on reaction with an acid.

Which compound when tested with silver nitrate solution gives no precipitate?
all the organic compounds and nitrates of metals and ammonium do not form ppts with silver nitrate.
What is half saturation test of starch?
With 2ml of starch solution 2ml of saturated ammonium sulphate solution is added. Formation of gelatinous precipitate gives confirmation of presence of starch
What is the principle of neumann test for casein?
Specific test for casein.when boiled with conc.HNO3 organic phosphorus in casein will be converted to inorganic phosphorus which gives yellow canary precipitate of ammonium phosphomolybdate
What salt gives a white precipitate when treated with barium chloride?
Nothing - barium chloride is soluble. You can however precipitate either the barium (e.g. with sodium sulphate, giving barium sulpate, or the chloride, e.g. with silver nitrate giving silver chloride precipitate.
Is ammonium nitrate covalent or ionic bond?
Ammonium nitrate has an ionic bond. Ammonium has an overall charge of 1+, making it a positive cation. Nitrate has an overall charge of 1-, making it a negative anion. When bonded together, nitrate gives ammonia an electron, resulting in an ionic bond being formed between them.
What is an atom that gives up electrons?
A cation
What is the precipitate color of silver nitrate and barium chloride?
Silver chloride (AgCl) gives a white precipitate. Silver Bromide (AgBr) also gives a white precipitate, though it's a slightly more creamy white than the precipitate formed by AgCl. Silver iodide (AgI) gives a pale yellow precipitate.
Is ammonium hydroxide a non volatile liquid?
No, ammonium hydroxide is highly volatile and gives out ammonia gas.
What is the reaction of n-butyllithium with ammonium chloride?
when nbutyl lithium is react with ammonium chloride gives LiCl and butane ,ammonia
Is lithium a cation or anion?
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
