19. Suppose the students had mixed a 12.5 g sample of Margarine B and a 12,5 a samplerde Margarine C. Further suppose that they had tested this mixed sample following the procedure
from Experiment 1. Based on Table 1. predict the most likely mass, in grams, of water in the
mixed sample. Explain your answer using specific numbers from Tablel.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
