Calculate the percentage change of pH for the water
Calculate the percentage change of pH for the water using the formula below
Percent Change of pH = 100% x ( pH at 5 drops – pH at 0 drops ) / ( pH at 0 drops )
100% X (12.18 -7.00)
7.00
2.Calculate the percentage change for the buffer using the formula below
Percent Change of pH = 100% x ( pH at 5 drops – pH at 0 drops ) / ( pH at 0 drops )
100% X (7.04 -7.00)
7.00
