Lead chloride isn't very soluble in the first place. I'm a little mystified as to what you think hydrogen gas has to do with it, though.

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.
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 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)
Why is it important to have ions in a solution to conduct electricity?
For electricity to be conducted through a solution, the solution needs to be polar or have ions in it. Electricity can be conducted through water because water forms a polar covalent bond. This means that the Oxygen's electronegativity (it's ability to attract electrons) is so great that is controls the electrons in the bond with hydrogen, giving the Oxygen a partial negative charge and Hydrogen a partial positive charge. When ions are dissolved into solution, they have much larger charges than the covalently bonded H2O molecules. Because of this, electricity (which has a negative charge) can easily 'jump' from one positive ion to the next to get itself through the solution, making the solution a much stronger conductor of electricity.
How can you separate solid solute from a liquid solvent?
The solvent is evaporated and after this condensed.
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.
What do hydrogen sulphide and copper sulphate form when mixed together?
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.

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 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 .

How does acid strength affect electrical conductivity?
The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.
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.
What do you observe when ethyne is passed through ammoniacal cuprous chloride solution?
A red-brown precipitate of copper acetylide is formed.
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
What happens when carbon dioxide gas is passed through calcium hydroxide solution?
When carbon dioxide gas is passed/bubbled through aqueous calcium hydroxide (also known as 'limewater'), a white precipitate will be formed. This means that the solution will turn cloudy/milky due to the formation of that white precipitate.Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)The precipitate, calcium carbonate, is only sparingly soluble in water. It will exist as a suspension in the resulting solution.But when excess carbon dioxide is added, this reaction takes place instead:CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)The calcium carbonate undergoes further reaction with water and carbon dioxide to form calcium bicarbonate (or calcium hydrogen carbonate), which is soluble. Thus the precipitate appears to 'disappear' or 'dissolve'. Thus, a colourless solution is formed.----- Other answers -----Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate (PCC):if carbon dioxide is passed through it it will turn cloudy and if it is done for to long then it will turn colourless.
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?
yellow
