Answer : The correct option is, pH meter

Explanation :

pH meter : It is a type of instrument which measures the activity of hydrogen ion in water based solution. Or we can say that it will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.

Litmus paper : It is a type of paper which changes the color based on whether the solution is an acid or a base.

Phenolphthalein : It is an indicator which changes the color based on pH values.

Bromthymol blue : It does not tell the concentrations, it is a pH indicator for the weak acids and bases.

Hence, the pH meter provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.

3) In the Hydrolysis of Disaccharides and Polysaccharides portion of the lab, starch should give one positive iodine test and on
AfilCa [17]

Answer: potassium iodide is the basic test for starch,and the positive test is blue-black coloration, any other test substance which is not starch will give a negative results.

Explanation:

Starch is an example of  polysaccharide  and since the standard test for it is potassium iodide solution, it gives a positive test.

Diasaccharides e.g maltose are reducing sugars.their standard test is BENEDICT test .

Therefore, in the hydrolysis;  starch should give a positve test, while Diasaccharides should give negative rest.
