Question

which of the following combinations is not suitable for making a buffer?
h3po4 and nah2po4
na2co3 and nahco3
nh4cl and nh3
nah2po4 and na2hpo4
hclo4 and naclo4
The last one and here's a tip. Don't forget where the shift key is for formulas (and starting a sentence for that matter). na2co3 doesn't mean a thing. CO is different than Co is different than co. Carbon monoxide vs cobalt vs company.
