WebOct 27, 2024 · How do we proceed? We add precisely measured amount of reagent A to sample and once the reaction ends we titrate excess reagent A left with reagent B. Knowing initial amount of reagent A and amount that was left after the reaction (from titration) we can easily calculate how much reagent A was used for the first reaction. fiberglass shaker exterior doorWebFrom the diagram, we can start with the titration first and determine the amount of NaOH used. Then using mole ratio from reaction 2, we can work backwards (hence the name back titration) and determine the amount of H2SO4 that reacts with NaOH. We can also calculate the total amount of H2SO4 used. derby recWebJan 20, 2013 · How to do back titrations - also known as indirect titrations.
