A sample of black coffee was measured to have [h3o+] = 7.94 × 10−6. what is true about this solution?
Sveta_85 [38]
Being given the hydronium (or simply the hydrogen) ion concentration (molarity), one of the easiest properties of the solution to determine is its pH. The pH of a solution indicates the acidity (or basicity) of a given solution. The typical pH range of solutions is from 1 to 14, with 7 being neutral, 1 to 6 being acidic, and 8 to 14 being basic. 

To determine the pH of a solution, the negative log (-log) of the hydronium/hydrogen ion concentration (molarity) of the solution is calculated. Thus (assuming that the given hydrogen ion concentration is in molarity (mol/L)),

             pH = -log(H^{+})          or          -log(H_{3} O^{+}
             pH = -log (<span>7.94 × 10−6 mol/L) 
             pH = 5.13

Because the pH is less than 7 (within the range 1 to 6), then the black coffee solution is acidic. </span>
