Concept Introduction:
A molecule or ion capable of losing a proton is known as an acid. An acid that partially dissociates into its ions in water or an aqueous solution is known as a weak acid whereas a strong acid fully dissociates into its ions in an aqueous solution or water.

The acidity of a solution is measured by its pH.
If Ht represents the concentration of hydrogen ions (in moles/liter) in the solution,
the pH is defined by pH = – log H+
Based on careful measurements and calculations, a chemist examines two solutions and asserts:
"The hydrogen ion concentration of Solution A
is 158 times greater than
the hydrogen ion concentration of Solution B."
If the pH of solution B is 3.4, determine the pH of Solution A.
Report your answer to one decimal place.
Solution A has pH equal to
Number
(Report to the nearest 0.1)
Is H2Cr2O2 an acid, base, or neutral? please justify your answer with an equation showing its dissociation.
pH = −log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH-value of less than 7 are acidic; solutions with a pH-value of greater than 7 are basic; solutions with a pH-value of 7 (such as pure water) are neutral.
Black coffee has a pH of 5 and pure water has a pH of 7. Compare the pH of each and determine how much more acidic black coffee is than pure water.
