If you were given an unknown solution and no ph paper, could you determine whether it is acidic, basic or neutral using only the three indicators? (phenolphthalein, bromthymol blue and methyl red) explain?

The three given indicators can be used for testing whether the given solution is acidic, basic or neutral.

Phenolpthalein: It shows fuchsia color if the solution is basic in nature and remains colorless if the solution is acidic in nature.

Bromophenol blue : It shows yellow color in acidic solution and purple color in  basic solution.

Methyl red: It is red in acidic solution and yellow in basic solution.

If the solution is neither acidic nor basic then definitely it is neutral.

answer; polycythemia is the correct answer;

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
