Question

Name the following ionic compounds: (a) K2Cr2O7, (b) Li2C2O4, (c) CuNO3.

Answer 1

Answer :

(a) The name of $K_2Cr_2O_7$ is, potassium dichromate.

(b) The name of $Li_2C_2O_4$ is, lithium oxalate.

(c) The name of $CuNO_3$ is, copper nitrate.

Explanation:

Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.

(a) $K_2Cr_2O_7$

The given compound $K_2Cr_2O_7$ is an ionic compound. It is made up of two different ions which are potassium ion $(K^+)$ and dichromate ion $(Cr_2O_7^{2-})$.

So, the name of $K_2Cr_2O_7$ is, potassium dichromate.

(b) $Li_2C_2O_4$

The given compound $Li_2C_2O_4$ is an ionic compound. It is made up of two different ions which are lithium ion $(Li^+)$ and oxalate ion $(C_2O_4^{2-})$.

So, the name of $Li_2C_2O_4$ is, lithium oxalate.

(c) $CuNO_3$

The given compound $CuNO_3$ is an ionic compound. It is made up of two different ions which are copper ion $(Cu^+)$ and nitrate ion $(NO_3^{-})$.

So, the name of $CuNO_3$ is, copper nitrate.
