Answer 2

Red litmus paper will stay red for the first test tube, blue for the second test tube, red for the third test tube and red for the fourth test tube as well. (Option A)

• First of all,the red litmus paper will stay red in acidic solution and will turn into blue in the basic solution.

• Now,in the first test tube,there is milk which is slightly acidic (pH around 6) and that's why the litmus paper stays red.

• Now,in in the second test tube there is baking powder solution which is basic and that's why litmus paper turns blue.

• Now,in the third test tube there is vinegar solution and that's why the litmus paper stays red.

• And,in the fourth test tube there is glucose solution which is also slightly acidic and that's why the litmus paper stays red.
