Answers
Answer:
Answer:-A You will get a cloudy white solution formed by insoluble silver chloride, AgCl. Gradually, the solid AgCl particles will settle to the bottom of the beaker, and gradually they will turn a slight "purplish" color since Ag is sensitive to light and some Ag in AgCl is reduced to silver metal
Answer:- B When ammonium chloride is heated with a solution of sodium hydroxide it leads to the formation of three products namely sodium chloride, ammonia and water. The reactant ammonium chloride and sodium hydroxide are solid and their chemical formula are and respectively
ANSWER C
Iron (III) sulphate + ammonium hydroxide gives iron (III) hydroxide and ammonium sulphate.
A reddish brown precipitate is observed and Fe(OH)
3
is insoluble in excess aq. ammonia / ammonium hydroxide
ANSWER :- D
When an excess of sodium hydroxide is added to calcium nitrate solution then, a white ppt of Ca(OH)2 is obtained that remains insoluble in excess of NaOH. ... Iron (III ) sulphate gives reddish brown ppt with ammonium hydroxide insoluble in excess
Answer:-E
If a little sodium hydroxide solution is added to colourless lead(II) nitrate solution, a white precipitate of lead(II) hydroxide is produced
.
Answer:-F
Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s).
