Question

An element X form a hydroxide X(OH)3 [3]
(i) Find the valency of X
(ii) Write the formula of its carbonate
(iii) Write the formula of its chloride

Answer 1

Answer:

1. Valency of x = 3
2. X(CO3)3
3. XCl3

Answer 2

An element X form a hydroxide X(OH)3.

• So, valency of X is 3.

Now, formula of carbonate will be :

$\boxed{carbonate \: : \: X_{2}(CO_{3})_{3}}$

• This is because : X has valency 3 and carbonate radicle has valency 2.

Now, formula of chloride:

$\boxed{chloride \: : \: XCl_{3}}$

• This is because , X has valency 3 and chloride ion has valency 1.
