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 happens when you add more NH4Cl to Magnesium hydroxide?
When you add more NH4Cl to magnesium hydroxide, the ammonium chloride will dissociate into NH4+ and Cl- ions in the solution. The NH4+ ions can react with the hydroxide ions from magnesium hydroxide to form ammonia gas and water. The excess ammonia gas will escape as it is a volatile compound.
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
When bases are dissolved in water an excess of which negative ion is produced?
Negative hydroxide, OH-, is formed though not in excessbut in equal (stoechiometric) or in even smaller amounts (i.c.o. weak bases).Base molecules gain protons (H+) from water (H2O) thus forming (leaving) OH- ions:B- + H2O --> HB + OH-You see that there never can be more OH- formed than base (B-) added.
Aluminium hydroxide is found in what?
Aluminium hydroxide is commonly found in antacids and as an adjuvant in vaccines. It is used in antacids to neutralize excess stomach acid and in vaccines to enhance the body's immune response to the vaccine.
Why do the solution of the white precipitate of Zinc hydroxide dissolve in excess of Ammonium hydroxide?
The white precipitate of zinc hydroxide dissolves in excess ammonium hydroxide because of the formation of the complex ion [Zn(NH3)4]2+. This complex ion is soluble in water, leading to the dissolution of the precipitate. The excess ammonium hydroxide provides additional ammonia molecules to form more of the soluble complex ions, increasing the solubility of zinc hydroxide.
Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?

Aluminum sulfate reacts with ammonium hydroxide to form what?
it forms a white precipitate ; Al(OH)3 and ammonium sulfate with additional excess NH4OH,still white ppt wont dissolve this means Aluminum dont make a complex with ammonia
When excess of ammonia is added to aqueous zinc sulfate does the precipitate dissolve?
Yes. The ammonia will form ammonium hydroxide. The ammonium cation (NH4+) will react with SO4^2- to form the soluble salt ammonium sulfate, (NH4)2SO4. According to Le Chatelier's Principle, this will push the reaction to the right, thus forming more ammonium sulfate from the insoluble zinc sulfate.
What happens when excess hydroxide solution is added to copper II sulphate solution?
When excess hydroxide solution is added to copper II sulphate solution, a precipitate of copper II hydroxide forms. The balanced chemical equation for this reaction is CuSO4 + 2NaOH -> Cu(OH)2 + Na2SO4. In this reaction, the blue color of the copper II sulfate solution turns into a light blue precipitate of copper II hydroxide.
What happens when EDTA is added to a solution of ammonia and copper sulphate?
When EDTA is added to a solution of ammonia and copper sulfate, it forms a complex with the copper ions, displacing ammonia from the solution. This results in the formation of a stable, water-soluble complex known as a copper-EDTA complex. The copper ions are effectively chelated by EDTA, which prevents them from reacting further.
What happens when you add more NH4Cl to Magnesium hydroxide?
When you add more NH4Cl to magnesium hydroxide, the ammonium chloride will dissociate into NH4+ and Cl- ions in the solution. The NH4+ ions can react with the hydroxide ions from magnesium hydroxide to form ammonia gas and water. The excess ammonia gas will escape as it is a volatile compound.
What is the effect of excess of sulphate ions in drinking water?
Excess of sulphate ions in drinking water can give it a bitter taste and cause gastrointestinal issues like diarrhea in some people. High levels of sulphate can also have a laxative effect and may impact the taste and quality of the water.
How do you Convert ammonium nitrate to anhydrous ammonia?
To convert ammonium nitrate to anhydrous ammonia, you need to heat the ammonium nitrate to a high temperature (above 170°C) in the presence of a catalyst such as activated carbon. This process will cause the ammonium nitrate to decompose into nitrous oxide and water vapor, leaving behind anhydrous ammonia as a gaseous product. The ammonia gas can then be collected and condensed for use.
Why only magnisium sulphate and calcium sulphate cause hardness of water not sodium sulphate?
Magnesium sulfate and calcium sulfate cause hardness in water because they are slightly soluble in water, leading to the presence of excess ions in the water. Sodium sulfate, on the other hand, is highly soluble and does not produce excess ions that contribute to water hardness.
How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
What are the effects of excess sulphate in drinking water?
Excess sulphate in drinking water can cause a laxative effect, leading to diarrhea or gastrointestinal discomfort in some individuals. Additionally, high levels of sulphate can impact the taste of the water, giving it a bitter or metallic taste. It is important to monitor sulphate levels in drinking water to ensure they are within safe limits.
