What else can I help you with?
What metal reacts with water to give a solution which forms a white precipitate with carbon dioxide?
Calcium. It reacts with water to form a solution of calcium hydroxide which can then react with carbon dioxide to form calcium carbonate, a white precipitate. You will get similar results with strontium and barium.
What happens when hydrogen sulphide passes through cadmium chloride?
when H2S gas i.e. hydrogen sulphide gas is passed through cadmium chloride solution, yellow colored precipitate of cadmium sulphide (CdS) is formed and aqueous hydrochloric acid (HCl) is formed. H2S(g) + CdCl2(aq) -----> CdS(s) + 2HCl(aq)
Will precipitate dissolve in water?
It depends on the type of precipitate. Some precipitates will dissolve in water, while others may not. Precipitates that are soluble in water will dissolve, forming a solution, while insoluble precipitates will not dissolve and remain as solid particles suspended in the water.
How insoluble salt can be recover?
Insoluble salts can be recovered through precipitation reactions by mixing two soluble salts that will react to form the insoluble salt as a precipitate. The precipitate can then be filtered out from the solution. Alternatively, the insoluble salt can be recovered by evaporating the solvent to concentrate the solution and allow the salt to crystallize out.
What is the green precipitate in preparation of chromium oxalate complexes?
No green precipitate should found but green but green heavy solution that can be filterated through the filter paper but white crystaline precipitate in a shape of needle or cylindrical flakes .
What is the test for hydrogen iodide?
Hydrogen iodide can be tested using silver nitrate solution. When hydrogen iodide is bubbled through silver nitrate solution, a yellow precipitate of silver iodide is formed. This confirms the presence of iodide ions in the sample.
Can a precipitate be separated from a solution by filtration?
Yes, a precipitate can be separated from a solution by filtration. The solid precipitate is trapped on the filter paper during the filtration process, while the liquid component (the filtrate) passes through.
If air is bubbled through hydrogen carbonate solution which is then poured into a test tube with small snails what colour would it change to?
The hydrogen carbonate solution would turn cloudy white due to the formation of calcium carbonate precipitate as a result of the reaction between hydrogen carbonate and calcium ions in the snails' shells.
What metal reacts with water to give a solution which forms a white precipitate with carbon dioxide?
Calcium. It reacts with water to form a solution of calcium hydroxide which can then react with carbon dioxide to form calcium carbonate, a white precipitate. You will get similar results with strontium and barium.
Hydrogen sulfide gas is bubbled through a solution of iron III chloride what is produced?
When hydrogen sulfide gas is bubbled through a solution of iron III chloride, it forms iron III sulfide as a solid precipitate. This reaction is represented by the chemical equation: FeCl3 + 3H2S -> Fe2S3 + 6HCl.
What happens when hydrogen sulphide passes through cadmium chloride?
when H2S gas i.e. hydrogen sulphide gas is passed through cadmium chloride solution, yellow colored precipitate of cadmium sulphide (CdS) is formed and aqueous hydrochloric acid (HCl) is formed. H2S(g) + CdCl2(aq) -----> CdS(s) + 2HCl(aq)
What a filter funnel and paper used for?
Usually, it's used to separate a precipitate from the liquid in the solution. The filter paper is folded into quarters and placed in the funnel. The solution is then poured onto the filter paper, where the liquid filters through and the precipitate stays on the filter paper. The precipitate can then be saved or discarded, depending on which part of the solution you want.
What is equation for Hydrogen sulfide gas is bubbled through a solution or iron chloride?
H2S + FeCl2 --> FeS + 2 HCl The iron sulfide will precipitate out, making this reaction nonreversible.
Will precipitate dissolve in water?
It depends on the type of precipitate. Some precipitates will dissolve in water, while others may not. Precipitates that are soluble in water will dissolve, forming a solution, while insoluble precipitates will not dissolve and remain as solid particles suspended in the water.
What is precipitation from homogeneous solution?
precipitation from homogeneous solution is a method to get pure and fine precipitate...that is he quality of the precipitate is increased through several parameters...in the precipitate formation we have two reactants....one is precipitating agent another one is analyte....in this method we are slowly producing any one of the above reactants through some chemical reactions....hence the excess super saturation decreases and crystal growth happens slowly...as a result fine crystals are formed
Do sodium and carbonate precipitate?
Sodium and carbonate ions typically do not form a solid precipitate when combined in solution, as both are usually soluble in water. However, they can form a white precipitate of sodium carbonate if carbon dioxide gas is bubbled through the solution, leading to the formation of insoluble sodium bicarbonate, which then decomposes to form sodium carbonate and water.
Can you separate hydrogen in the sodium chloride solution?
NaCl itself will not render any hydrogen, however you can separate hydrogen from the water through the process of electrolysis. During electrolysis of NaCl solution, hydrogen will be evolved at cathode.
