0.84 g of metal carbonate reacts completely with 40 ml of H2SO4. What is equivalent weight of the metal-
Solution: weight of metal carbonate/GEW = NaXVa in lt 0.84/GEW = 0.5X40/1000 GEW of metal carbonate = 42 GEW of Metal = 42 - GEW of CO3-2 = 42-30 = 12g

How will you test for the gas which is liberated when hydrochloric acid reacts with an active metal?
When an active rnetal like Zn reacts with HCl, the gas produced burns with a pop sound which indicates that it is hydrogen gas. Zn(s) + 2HCl(aq) -----> ZnCl2(s)+ H2(g)

Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid,whereas copper does not. Explain why?
Zinc is above hydrogen rvhereas copper is below hydrogen in the activity series of metals. That is why zinc displaces hydrogen from dilute hydrochloric acid, while copper does not. ...

Name a metal When calcium metal is added to water the gas evolved does not catch fire but the same gas evolved
In both cases, the gas evolved is H2. When calcium reacts with water the heat evolved is not sufficient for hydrogen to catch fire. On the other hand, sodium metal...
