2 Calculate the pH of each of the following solutions, and label each as acidic, basic, or neutral. Solution Concentration [H0] 1.0 x 109 M PH Acidic/Basic/Neutral [H,O]=0.001 M [H,O] 3.7 x 10-6 M =>

Discuss how buffers help prevent drastic swings in pH.

Which of the following statements is true? Acids and bases cannot mix together Acids and bases will neutralize each other Acids, but not bases, can change the pH of a solution Acids donate hydroxide ions (OH-); bases donate hydrogen ions (H+).

The pH of black coffee is 5, and that of milk of magnesia is 10. Is the coffee twice as acidic as milk of magnesia?

Using a pH meter, you find the pH of an unknown solution to be 8.0. How would you describe this solution? a. weakly acidic b. strongly acidic c. weakly basic d. strongly basic

Some undiluted acids are not as corrosive as when they are diluted with water. That is why lab workers are told to wipe off splashes with a towel before washing. Explain.

Ty is three years old and as a result of a stomach bug has been vomiting for about 24 hours. His blood pH is 7.48. What does this mean? Tys blood is slightly acidi Tys blood is slightly alkaline. Tys blood is highly acidi Tys blood is within the normal range
