Question

identify the cationic and anionic radical in given unknown salt A by performing dry and wet test for cationic radical and anionic radical

Answer 1

Heya friend !

Cation is a positively charged radical, whereas Anion is a negatively charged radical.

let the given unknown salt be sodium chloride(NaCl) as we know.

This procedure of detecting/ finding whether the radical is cation or anion is called Cation analysis and anion analysis.

Dry tests are those which are performed with the solid state ( or the mixture of salts)

while,

wet tests are those tests which are performed by dissolving the salts or mixture of salts.

The answer would be, I think,

sodium is positively charged..so it is cation..

whereas chloride ion is negatively charged...so it is anion..

we can tell whether these are positive or negative by their respective valencies.

I tried to reach you what I know.

Hope it gives atleast an idea for you...

Thank you...
