WebAccording to the Lewis definition, acids are molecules or ions capable of coordinating with unshared electron pairs, and bases are molecules or ions having unshared electron pairs available for sharing with acids. To be acidic in the Lewis sense, a molecule must be electron deficient. This is the most general acid base concept.

WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. how to survive saturnWebAcids are substances that provide hydrogen ions (H +) and lower pH, whereas bases provide hydroxide ions (OH –) and raise pH.
