I/GCSE Chemistry Question Analyses Topic: Chemistry - Short Questions
Exam Question:
1) Write two differences between ideal solutions and non-ideal solutions.
2) Write one similarity between physisorption and chemisorption.
3) What type of colloid is formed when a gas is dispersed in a liquid? Give an example.
Answer:
For I/GCSE Chemistry, you should know:
1) Ideal solutions are those that adhere to Raoult's law, whereas non-ideal solutions do not.
In an ideal solution, the interaction between the solute and the solvent particles is the same as the interaction between the solute and the solvent, but in a non-ideal solution, it either increases or decreases.
2) Both physisorption and chemisorption are exothermic processes.
3) Foam is the type of colloid that develops when gas is spread in a liquid.
Examples include whipped cream and shaving cream.
Work hard for your I/GCSE Chemistry examination!
End of analysis. Great!
