Lecture 10 Flashcards
What is the process of adding water to a concentrated or stock solution to achieve the molarity desired for a particular solution called?
dilution
T or F: Dilution with water does not alter the number of moles of solution present
True
What is the equation for dilutions?
m1v1=m2v2
What are the three different types of reactions in aq solutions?
- precipitation reactions
- acid-base reactions
- oxidation-reduction reactions
What are the characteristics of a precipitation reaction?
- rules of solubility control what happens
- a solid forms and comes out in the solution
What does it mean if something is soluble?
It dissolves in the solution (aq)
What does it mean if something is insoluble?
