The pH level, given the molar hydrogen ion concentration, can be determined using the equation
pH = –log10[H+]
where pH represents the pH level while H+ represents the molar hydrogen ion concentration.
The acceptable pH range for a particular acidic solution is between 1.2 and 1.5. What is the interval of molar hydrogen ion concentration of this acid solution?
(0.0032, 0.0063)
(-∞, 0.0032) ∪(0.0063, ∞)
(0.0316, 0.0631)
(-∞, 0.0316) ∪(0.0631, ∞)
