The prepartion of Lead sulphate from Lead carbonate is a two steps process.
(Lead sulphate cannot be prepared by adding dilute Sulphuric acid to Lead Carbonate.)
i) What is the first step that is required to prepare Lead sulphate from Lead carbonate?
ii) Write the equation for the reaction that will take place when this first step is carried out.
iii) Why is the direct addition of dilute sulphuric acid to Lead carbonate an impractical method of preparing lead sulphate.
i) Treatment with nitric acid to form soluble lead nitrate.
ii) PbCO3+ 2HNO3 ---> Pb(NO3)2 + H2O +CO2
insoluble soluble
iii) Direct addition of dil. Sulphuric acid to lead carbonate will lead to deoposition of lead sulphate on the surface of lead carbonate which stops further reaction of sulphuric acid on it.
Dilute Nitric acid is generally considered a typical acid except for its reaction with metals. In what way is dilute Nitric acid different from other acids when it reacts with metals?
What is observed when:-
Neutral litmus solution is added to sodium hydrogen carbonate solution.
Acid dissolves in water to produce positively charged ions. Draw the structure of these positive ions.
Electrons are getting added to an element Y.
I) Is Y getting oxidized or reduced?
II) What charge will Y have after the adition of electrons?
III) Which electrode will Y migrate to during the process of electrolysis?
