A low pH means very acidic. Very acidic means lots of hydronium ions. Which molecule will produce the most hydronium ions once dissolved?

anonymous · Answer

Well, H2O would be a nutral pH.

anonymous · Answer

Well, I believe that H3PO4 is the correct answer. @matt101 , @Apocalyptic_Ash

anonymous · Answer

I believe it may be the correct answer

anonymous · Answer

I was thinking that too. :) Let me check my chart.

matt101 · Answer

Then you'd be right!

Water is neutral as @Apocalyptic_Ash says, so it's not likely to form a significant amount of hydronium or hydroxide ions. NaOH and KOH are both bases, because they dissociate in water to produce hydroxide ions.

So, H3PO4 is correct? @matt101
