Commercial Preparation of Hydrogen

Q.

How is Hydrogen used in Everyday Life?

Q.

Let ${\mathrm{C}}_{\mathrm{NaCl}}$ and ${\mathrm{C}}_{{\mathrm{BaSO}}_4}$be the conductances

1. ${\mathrm{C}}_{\mathrm{NaCl}}\left({\mathrm{T}}_2\right)>{{\mathrm{C}}_{{\mathrm{BaSo}}_4}}_{}\left({\mathrm{T}}_1\right)$for ${\mathrm{T}}_2>{\mathrm{T}}_1$

2. ${{\mathrm{C}}_{{\mathrm{BaSo}}_4}}_{}\left({\mathrm{T}}_2\right)>{{\mathrm{C}}_{\mathrm{NaCl}}}_{}\left({\mathrm{T}}_1\right)$for ${\mathrm{T}}_2>{\mathrm{T}}_1$

3. Ionic mobilities of ions from both salts increase with T

4. ${\mathrm{C}}_{\mathrm{NaCl}}>>{{\mathrm{C}}_{{\mathrm{BaSo}}_4}}_{}$ at a given T

Q.

6) State two important uses of following non -metal

(c) Chlorine

Q. $M$ is a metal above hydrogen in the activity series and its oxide has the formula $M_{2}O$. This oxide when dissolved in water forms the corresponding hydroxide which is a good conductor of electricity. In the above context answer the following:
Name the product at the anode?
