1: Purpose

find the ph of [acid]

2: procedure

STEP one: weight the mass of the candy we used( tartaric acid)

STEP two: mash to make powder

STEP three: Get the water we need to use to dissolve our acid(50ml)

STEP four: dissolve our acid into our water

STEP five: get things ready for the titration

STEP six: titrate 10ml of our sample at a time(three times)

 

3:materials

1):acid(tratric acid)

2): Grinding bowl

3):things for titration(burettea, Erlenmeyer, titrant)

4: Data & calculation

 

6:conclusion

pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH.
