Iimpawu zeMichiza: iikristale ezinokukhanya okuluhlaza, umgubo obomvu obomvu emva kokusila.Inyibilika etywaleni kunye nesisombululo sesodium hydroxide, inyibilika kancinane emanzini.
Ukusetyenziswa: i-asidi-base ekhuthaza i-arhente.Yenza isisombululo se-0.1% okanye i-0.04% isisombululo se-aqueous nge-20% ethanol (diza i-0.04g yale mveliso kwi-1.05ml ye-0.1M isisombululo se-NaOH), uze uhlambulule kwi-100ml.Uluhlu lokutshintsha umbala we-pH: 7.2 (ophuzi) -8.8 (omfusa);2.0 (bomvu)-3.0 (i-amber).
