Dissolving an Unknown Acid Salt - Weak Acids?

[ppkjref]

i'm trying to dissolve an unknown acid salt and it is not soluble in water at stp. it does dissolve, however, when it undergoes heat and some stirring. is this property representative of most weak acids, that they are not easily miscible in water?

Most weak acids are organic substances - some are miscible, some are weakly soluble. I don't think it is a "representative property" of weak acids as such.
