Ħawwad it-taħlita billi tuża aġitatur manjetiku (3.2.16), żid ftit qtar ta' porpra tal-bromokresol (3.2.5) u żid it-taħlita ta' l-ammonja mħallta bl-ilma (3.2.9) sakemm il-kulur isir vjola (it-taħlita hija aċidu dgħajjef mill-fdal ta' aċidu aċetiku wżat fit-tlaħliħ).
stir the solution using a magnetic stirrer (3.2.16), add a few drops of bromocresol purple (3.2.5) and add the diluted ammonia solution (3.2.9) until the colour turns violet (the solution is weakly acid from the residue of acetic acid used for rinsing).
