In this chapter, you can expect questions where you have to carry out calculations on volume strength of hydrogen peroxide. Hydrogen peroxide forms a hydrate when mixed in water. When solving questions related to strength of hydrogen peroxide, remember these points:
- 'X' volume of 'Y%' hydrogen peroxide means that 1 millilitre of the solution will give 'X' mL of oxygen at STP. 1 litre solution will give 10 litre of oxygen. 1 ml solution will give 10 mL of oxygen.
- Here's the chemical equation behind this decomposition: . According to this, 1 mole of = 2 moles of
- At STP, one mole of oxygen occupies 22.7 litres.
- Shortcut for molarity: If molarity of a solution is M, then its volume strength will be 11.2 X M.
- Shortcut for normality: If normality of a solution is N, then its volume strength will be 5.6 X N.
Here's a question you can solve:
The volume strength of solution is:
