Solubility in Water Quiz
Rated 3.5 out of 5
3.5 out of 5 stars (based on 2 reviews)
This quiz is mainly aimed at Edexcel students. Most other courses can skip this and move on to another chemistry quiz.
Warning: This quiz is quite difficult and to pass you’ll need to remember the rules determining if a salt is soluble. Be patient, it might take a few tries. Try to remember the rules and not just guess the answers.
Soluble means that the salt will dissolve in water to form a solution. Insoluble means it won’t.
Good Luck!
