Brad is testing three solutions with litmus paper. after dipping the litmus paper strips in the solutions, he observes two papers turning blue and one turning red. out of the three solutions, how many are acidic?

one solution is acidic

Explanation:

Acid base indicators are usually weak acids or weak bases. They change their color in the solution with change in the pH.

For any indicator say HIn , the dissociation can be shown as:

Litmus is one such indicator which turns red in acidic solutions, blue in alkaline solutions, and purple in neutral solutions.

Thus out of three solutions , the litmus paper strip is turning red in one solution, thus only one solution is acidic. the other two in which litmus is showing blue color are alkaline in nature.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
