<pre wrap="">Hi dr. Pounds
This is Michael tan and I had a question about about 4.30 in the textbook. I'm just confused about how you can determine whether the species is a bronsted acid or base without knowing the entire chemical formula?
Thanks for the help

<font face="serif">The ones that were ONLY Bronsted acids had a
proton to donate. The ones that were only bronsted bases did not
have a proton to donate, but needed a proton.<br>
<br>
The ones that were designated "both" were polyprotic weak acids.
They had already lost one proton, could potentially get it back,
and also could donate another one.<br>
