Acids, Bases And Preparation Of Salts
Through out our experiments in the past classes we have discovered that once you mix an acid with a base what you normally get is a salt. Test out your understanding of this topic by taking this review questions and tackle them with your fellow classmates. There will be a test to see if you took up this challenge.
