In the following question, wouldn't Li3PO4 also result in a basic aqueous solution?

Seems like it should to me since it has an anion that's not derived from a strong acid...

@FeralisExtremum according to Chad, it most certainly should be. This might be a mistake. I got this question right but I definitely had to spend some time thinking about (B.) as well

I don't want to muddy the water further but along with NaF and Li3PO4, K2SO4 is a basic salt too. It's easy to confuse this one as we might be tempted to think that SO42- is the conjugate base of a strong acid (H2SO4) but it's the conjugate base of HSO4-, a weak acid.

Hmm indeed...

Makes sense, my dude. NaF = NaOH & HF = basic salt.
Li3PO4 = LiOH & H3PO4 = basic salt.

Hmm..

NaF is a basic salt not because you form NaOH, which is a strong base and would readily dissociate, but because the F- reacts with H2O to yield HF + OH-.......right? I am also very curious as to why the other ones aren't basic as well.
