serial dilutions

Question 1

what is the aim of a serial dilution?

Answer 1

to find how much liquid is required to make a solution

Question 2

what is the formula for a serial dilution?

Answer 2

required concentration / conc of stock solution x final volume required = how much liquid to make solution

Question 3

what is another formula for serial dilution?

Answer 3

C1V1 = C2V2

C1 = conc of stock solution
V1 = volume of stock solution required to make new concentration
C2 = concentration of new solution
V2 = volume of new solution (volume of stock and water together)

Question 4

what is a dilution series?

Answer 4

a dilution series is the step by step dilation of a substance in a solution

Question 5

what do dilution series enable us to do?

Answer 5

● make solutions with very low conc without having to measure out very small volumes

● this will help improve accuracy
