What else can I help you with?
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 is an atom that gives up electrons?
A cation
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 lithium a cation or anion?
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
A reducing sugar gives a precipitate of silver metal with Benedict's reagent.?
This is probable an error.
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 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 does AgNO3 and NaCl gives?
When silver nitrate (AgNO3) is mixed with sodium chloride (NaCl), a white precipitate of silver chloride (AgCl) is formed. This reaction is a double displacement reaction where the silver cation from AgNO3 and the chloride anion from NaCl switch partners to form the insoluble AgCl precipitate.
What is an atom that gives up electrons?
A cation
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.
Is lithium a cation or anion?
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
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.
Is ethyl-ammonium nitrate and acid or a base?
Ethyl ammonium nitrate is a protic ionic liquid. It gives a slightly acidic pH of 5 at 298K, as documented in the reference.
