@leah4sci: Can pH be negative? You're used to seeing pH values between 0 and 14, so a negative pH sounds impossible. But what happens when the hydrogen ion concentration is greater than 1 M? In this video, I'll show you why negative pH is exactly what the equation predicts and why it's much easier to understand than memorize. 👍 If this finally made sense, give the video a like. #MCAT #GeneralChemistry #Leah4Sci #pH #AcidsAndBases
