1. The Brønsted-Lowry definition of an acid is D), acids donate electrons.
2. Similarly, their definition of an acid is C), acids donate the H+ ions to other basic substances
3. The formula for pH is: -log[H+]. in order to find the H+ in the equation, we need to take the antilog, which would give us another formula: [tex]10^{-pH} [/tex]. Just plug in the ph value and we get [tex]1.0*10 x^{-5} [/tex]. The closest answer to that would be C). I'm not sure if there's a typo there, but it should be 1 x 10^-5
