Izici zamakhemikhali: amakristalu anokukhanya okuluhlaza, impushana ebomvu ngokunsundu ngemva kokugaya.Incibilika otshwaleni futhi ixube isixazululo se-sodium hydroxide, inyibilika kancane emanzini.
Ukusetshenziswa: i-ejenti ekhuthaza i-acid-base.Yenza isixazululo esingu-0.1% noma isixazululo esingu-0.04% esinamanzi nge-ethanol engu-20% (ncibilikisa u-0.04g walo mkhiqizo ku-1.05ml wesixazululo esingu-0.1M NaOH), bese unciphisa ku-100ml.I-pH ishintsha umbala: 7.2 (ophuzi) -8.8 (onsomi);2.0 (bomvu)-3.0 (inhlaka).
