I thought perhaps people will have many chem doubts just b4 the exam, so I made this thread...its better if we have all chem question in one thread rather that making new ones for each question.I start:
1)Design and draw an apparatus that could be used to collect the volume of hydrogen produced when zinc is added to dilute hydrochloric acid.
2)A solution gives a white ppt which is soluble in excess with sodium hydroxide. Its reaction with aq. ammonia gives a white ppt which is insoluble in excess. Find out the cation present in the solution.
okay, so i know how to design the experiment(as in the description) but i wanted a neat diagram plss.
nd for the second question, there can be 2 answers- Aluminum and Lead.....so which one should i write??
