Best ResponseYou've already chosen the best response.1Which options do you know are true?

Best ResponseYou've already chosen the best response.1Yes D is true is because thats what the scale shows us how basic or how acidic your solution is

Best ResponseYou've already chosen the best response.1B is actual the not true one the entire scale involves powers of 10 so for example your solution has a pH of 1, that solution is 10x more acidic than a solution of pH2 and 100x more acid than a solution of pH3. The concentration of H+ ions is the same way so going back if you solution has a pH of 1 you have 10x the H+ ions than a solution of pH 2 and 100x more than a pH of 3

Best ResponseYou've already chosen the best response.0So that means A is true, and the answer is C?

Best ResponseYou've already chosen the best response.1A,C and D are all true B is not true because a pH of 4 does not have twice the H+ ions of a solution with a pH of 2. The solution with a pH of 2 would have 100x the H+ ions than the solution of a pH of 4

Best ResponseYou've already chosen the best response.0How about this one? I think either C or D.

Best ResponseYou've already chosen the best response.1Something to note about this is that the H+ and the OH are in aqueous form where the H2O is actually a liquid the H2O would not be present in the expression. If the H2O was not liquid but aqueous then it would be C but since it is a liquid your answer would be B

Best ResponseYou've already chosen the best response.1Ok so lets start off with the pH formula do you know what that is?

Best ResponseYou've already chosen the best response.0Yeah and I got A as my answer. Can you please check if that's right?

Best ResponseYou've already chosen the best response.1So the pH formula is pH=log[H+] you almost had it the right way but you have to include that negative so you would have 10^(6.89)=[H+] so your answer is C

Best ResponseYou've already chosen the best response.0Thanks! It's either B or D right? What is the pH of a solution whose [H+] = 5 × 108 M? A. 7.3 B. 8.0 C. 7.3 D. 8.0

Best ResponseYou've already chosen the best response.1Sorry nope! How did you come to the conclusion that it is either B or D?

Best ResponseYou've already chosen the best response.0Well doesn't pH have to be a multiple of 10?

taramgrant0543664

Best ResponseYou've already chosen the best response.1pH is not necessarily a multiple of 10. The only time it is in multiples of 10 is when you are talking about a solution of pH of 1 being 10x more acidic than the pH of 2 solution or the pH1 solution having 10x more H+ ions than that of a solution of pH2 In this case pH=log(5x10^(8))= a pH of 7.3

Best ResponseYou've already chosen the best response.0Ah, okay thank you! What is true of a BrønstedLowry acid? A. A BrønstedLowry acid donates H+ ions. B. A BrønstedLowry acid donates OH ions. C. A BrønstedLowry acid donates electrons. D. A BrønstedLowry acid donates a metal.

Best ResponseYou've already chosen the best response.1It would be A as it releases/donates H+ ions because it is a proton donor

Best ResponseYou've already chosen the best response.1I would say C as the combination should make a a salt and H2O
