What volume of 0.250mol/L solution could you make with 55.9g of potassium chloride,KCl(s)
Mercury compounds are poisonous, but mercury ions can be removed from a solution by precipitating insoluble mercury(ii) sulfide,HgS(s). Determine the minimum volume of 0.0783mol/L sodium sulfide, Na2S(aq), that is needed to precipitate all the mercury ions in 75.5mL of 0.100mol/L, Hg(NO3)2(aq)
