II. Experimental :
II. 1. Apparatus and Instruments :Beakers,glass rod,burner,digital PH meter .
II. 2. Materials :Different varieties of tea leaves.Following codes are used for different brand.

Brand Code 1. T1 2. T2 3. T3 4. T4
II.3. Procedure :
1. 4 gm of each tea samples were taken in separate beakers.
2. 20 ml of boiling water was added to each of the beaker and allowed to stand for 5 minutes.
3. Now PH of the liquor in each beaker was measured using digital PH meter.
II.4. Observations : Sample No | PH of the liquor | 1 | | 2 | | 3 | | 4 | |
Result and Discussion :

After analyzing the tea samples of different brands we found the acidity of the tea samples with the help of Ph meter. The acidity of the tea depends on the Ph value of the tea.As we know that if the Ph value of tea
