Best ResponseYou've already chosen the best response.1Use the second to find your hydrogen ion concentrations, you'll observe that the one with the lower pH has more hydrogen ions.

Best ResponseYou've already chosen the best response.1For the solution with a pH of 3.8, [H+] = 10^3.8 = 1.58 x 10^4 M For the solution with a pH of 6.2, [H+] = 10^6.2 = 6.31 x 10^7 M The solution with a pH of 3.8 has a higher hydrogen ion concentration.

Best ResponseYou've already chosen the best response.0how about if one solution has 100 times as many hydrogen ions as another solution, what is the difference, in pH units between the two solutions?

Best ResponseYou've already chosen the best response.1So heres another question if you wanna try it: If the pH of a solution is 8.5, what is the pH of a solution that has a 10000 times greater hydrogen concentration?

Best ResponseYou've already chosen the best response.1Its not your fault, I'm not really showing any work/explaining, sorry. Lets assume that solution A has a [H+] concentration greater than solution B. \[[H _{}^{+}]_{A}^{} = 10^{pH _{A}^{}}\] \[[H _{}^{+}]_{B}^{} = 10^{pH _{B}^{}}\]

Best ResponseYou've already chosen the best response.1If we divide the two equations, we get that \[[H _{}^{+}]_{A}^{} / [H _{}^{+}]_{B}^{} =10^{pH _{A}^{} + pH _{B}^{}} = 100\]

Best ResponseYou've already chosen the best response.1\[10^{pH _{A}^{} + pH _{B}^{}} = 100\] Take the log based 10 of both sides:\[\log_{10}( 10^{pH _{A}^{} + pH _{B}^{}} = 100)\] \[{pH _{A}^{} + pH _{B}^{}} = 2\]

Best ResponseYou've already chosen the best response.0oh i see it now thanks! i am getting it a little now but if you dont mind i have about two other problems that need to be completed, but i dont exactly want you to do it for me but help me lead myself to an answer if you dont mind?

Best ResponseYou've already chosen the best response.0if solution a contains 1 x 10^6 MH+ ions and solution B contains 1 x 10^8 MH+ ions, which solution contains more H+ ions

Best ResponseYou've already chosen the best response.1This question is just about your understanding of negative exponents I guess. Convert the numbers from scientific notation to standard notation to see which one is bigger.

Best ResponseYou've already chosen the best response.0ok dang i feel dumb now lol but do you know the relationship between hydrogen ion contrecations to the acidity and alklinity (basicity) of solution?

Rogue

Best ResponseYou've already chosen the best response.1An easier way to do this problem would be to look at the pH's of each solution. If you look at the [H+] equation and compare it to the values they give, you'll notice that the first solution has a pH of 6 whilst the second has a pH of 8.

Best ResponseYou've already chosen the best response.0so would the ph of 6 be greater right?

Rogue

Best ResponseYou've already chosen the best response.1Higher hydrogen ion concentration = lower pH = more acidity. Lower hydrogen ion concentration = higher pH = more basicity.

Rogue

Best ResponseYou've already chosen the best response.1Yup, the pH of 6 has more...

Best ResponseYou've already chosen the best response.0HA is an acid that ionizes 10% in a solution. what is the H+ of a 0.01 M solution of HA? what is its pH?

anonymous

Best ResponseYou've already chosen the best response.1If 10% of the 0.01 M is ionized, how much H+ are there?

anonymous

Best ResponseYou've already chosen the best response.0um yeah now ya got me

Rogue

Best ResponseYou've already chosen the best response.110% of 0.01 M is just 0.001 M, so that is you H+ concentration. pH =  log [H+] =  log (0.001) = 3

Best ResponseYou've already chosen the best response.1pH is often positive by the way, unless your dealing with a strong acid, or a super concentrated solution.

Best ResponseYou've already chosen the best response.0so would 3 be the pH or the HA? or the amount of H+?

Rogue

Best ResponseYou've already chosen the best response.1HA is just some arbitrary acid, H is for the hydrogen an acid has, and A is for acid.

Best ResponseYou've already chosen the best response.0alright so in this next problem it seems like its working backwards what is the H+ of a solution whose pH is 8? what is the OH?

Rogue

Best ResponseYou've already chosen the best response.1Use these equations to help you: pH + pOH = 14 pH =  log [H+] pOH =  log [OH] [H+] = 10^pH [OH ] = 10^pOH

Rogue

Best ResponseYou've already chosen the best response.1So for the first part, [H+] = 10^8 M. For the second part, you get pOH = 6, so then [OH] = 10^6 M
