Question 6

Titrant

Answer 6

In a titration, the solution of accurately known concentration

Question 7

Analyte

Answer 7

Substance or chemical constituent that is to be determined in an analytical procedure, like titration

Question 8

Equivalence point

Answer 8

The point at which the reaction is complete

Question 9

Indicator

Answer 9

Substance that changes color at or near the equivalence point called the end point

Question 10

End point

Answer 10

When you actually stop doing the titration, usually determined by indicator color change

Question 11

Molarity

Answer 11

M = moles of solute/ Liters of solution

M = molar mass/ liters of solution

M*V = moles
