d.a proton donor
e.a compound having hydrogen as a cation and oxygen as an anion

anonymous · Answer

i think its either c  or e

blues · Answer

It helps if you say why you think it is C or E. I actually think it is neither C nor E. An acid is anything which can donate a proton.

anonymous · Answer

i thought it was c or e .... because my book talked about  A type of compound that contains hydrogen and dissociates in water to .. so i thought it could be those

thanks so much though:

blues · Answer

It is how your book words it.

A hydrogen atom has one proton and one electron. Sometimes the electron gets taken away, leaving just the proton. So hydrogen atom without its electron = proton.

When hydrogen dissociates in water, it forms a proton. So in your book you can cross out "hydrogen" and write in "proton." For purposes of this discussion.
