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?
I) Reduced
II) Negative
III) Anode
What is observed when:-
Neutral litmus solution is added to sodium hydrogen carbonate solution.
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.
Acid dissolves in water to produce positively charged ions. Draw the structure of these positive ions.
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?
