Q

How can the concentration of acid to alkali be calculated

A

Through titration. You need a pipette a pipette filler , a conical flask and a burette ( to add small measured volumes of one reactant to another reactant in the conical flask)

Q

Method of titration

A
  1. Use pippete and filler to add 25 cm3 of alkali
  2. Add a few drops of indicator
  3. Fill the burette with acid and note starting volume
  4. Slowly add the acid from. Burette to alkali in the conical flask
  5. Stop adding acid when an appropriate Color change is reached in the indicator. Note final volume reading
  6. Repeat experiment several times
  7. Subtract final reading from original reading to get your titre and then calculate the mean titre
