Give the names of the cation in each of the following compounds: a. CuS b. Ag2SO4 c. Al(ClO3)3 d. CO(OH)2 e. PbCO3.

a. Cu2+  (Copper (II) ion )   b. 2Ag+ ( Silver ion)  c. Al3+ (Aluminium (III) ion)  d. Co2+  ( Cobalt (II) ion)   e. Pb2+ ( Lead (II) ion )

Explanation:

Cations are positively charged ions.

In the question given;

CuS , known as Copper (ii) Sulphide, has Cu2+ (Copper (II) ion ) as the Cation.

Ag2SO4, Known as Silver Sulfate, has 2Ag+ ( Silver ion) as the Cation.

Al(ClO3)3, known as Aluminium Chlorate, has Al3+ (Aluminium (III) ion), as the Cation.

Co(OH)2, known as Cobalt(II) Hydroxide, has Co2+ ( Cobalt (II) ion) , as the Cation.

PbCO3, known as Lead(II) Carbonate, has Pb2+ ( Lead (II) ion ), as the Cation.

A line of best fit can only be drawn if there is strong positive or negative correlation. The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.
