Choose the FALSE statement   An indicator can be used to monitor a buffer range   When pH equals PKa of weak acid, the buffer capacity is the greatest   Polyprotic acids have multiple stoichiometric points in their titration curve   At the mid-point of titration of weak acid by strong base, the pH of the solution -does not equal the pKa of the weak acid   The moles of titrant equals moles of titrate
