Benzene Carboxylic acid
« on: June 16, 2010, 04:30:55 PM »
How can you test that it's acidic, without using indicators?

If by indicators you mean specific indicators to test a compound for acidity or basicity.You can refrain it by Benzoic acid's reaction with acid and bases. As normally acid will react with base with it's affinity to give salt and water; And remains unreacted with acid + acid reaction.

It's a strange thing, but when you are dreading something, and would give anything to slow down time, it has a disobliging habit of speeding up.

By indicators I assume you mean phenolphthalein, methyl orange, etc. The best way to test for the acidity of a benzoic acid is to react it with a base like NaOH, which will spawn sodium benzoate via a neutralization reaction.

Is there something wrong with pH paper?

Simple: react it with sodium hydrogen carbonate solution, if you get CO2 formed then the compound is acidic!
