Help please with this question! Thank you! 1. Hydrocyanic acid (HCN) is a strong acid. In a water solution of this acid, which of the following would you expect to find more of? HCN OH H+(H3O+) HCN+

OpenStudy (aaronq):

write the reaction with water

OpenStudy (aaronq):

a strong acid means that the eq. will lie on the right side of the forward reaction.

OpenStudy (naturesweetie):

Do you mean something like this HCN+H20---- H30+CN-

OpenStudy (aaronq):

yes, exactly

OpenStudy (naturesweetie):

Using the equation would I take the result which is H30+CN- to the answer?

OpenStudy (aaronq):

we'll only one of the species of the products is in the questions

OpenStudy (aaronq):

in the answers**

OpenStudy (naturesweetie):

OH- is definitely not the answer.. Nor is HCN+... H+(H30+) is confusing me... It has the H30+ so would that be it?

OpenStudy (aaronq):

yep, \(H^+\) is a shortcut, the species in solution is actually \(H_3O^+\)

OpenStudy (naturesweetie):

Oh duh... I was missing the step in my head... Whoops... Thank you very much!!

OpenStudy (aaronq):
