What is the endpoint of a titration

• Where the amount of acid and base are balanced according to the equation
• Where there is no base
• At the end

If phenolphthalein turns bright pink, it indicates

• an acid 
• a base
• a neutral

Why do we perform a titration?

• To determine the concentration of an unknown solution

• To see if a reaction will occur between an acid and base

• To find the mass of an unknown acid

• To find the molar mass of an unknown solution

• To calculate the viscosity of the solution
