Some crystals form in acidic urine (pH < 7.0) while others form in alkaline urine (pH > 7.0). Ammonium urate- and amorphous urate crystals aren't dissolving in acetic acid but the addition from 10%ual acetic acid to the urine sediment which contain these crystals often leads to the appearance of uric acid- and sometimes to sodium urate-crystals (for further details see discussion about uric acid crystalluria).
