Hydrogen Test -...

$$H_{2}O_{2}$$ present in the atmosphere is formed by the action of sunlight on the atmospheric:

$$H_{2}O_{2}$$ forms prismatic crystals at:

The product obtained at anode when $$50\%\: H_{2}SO_{4}$$ aqueous solution is electrolysed using platinum electrodes is :

The melting point of most of the solid substances increases with an increase in pressure. However ice melts at a temperature lower than its usual melting points when pressure is increased. This is because:

Electrolysis of $$50\%\: H_{2}SO_{4}$$ produces:

In the preparation of $$H_{2}O_{2}$$ by auto-oxidation method, the starting substance is:

Which of the following compound gives $$H_{2}O_{2}$$ by the addition of $$H_{2}O$$?

Which one of the following compounds undergoes hydrolysis during distillations to yield hydrogen peroxide?

Assertion (A): Hydrogen shows resemblance with alkali metals as well as halogens.
Reason (R): Hydrogen exists in atomic form only at high temperature.
