EXAMPLE 1 â Predicting Precipitation Reactions: Predict whether a precipitate will form when water solutions of silver nitrate, AgNO 3 (aq), and sodium sulfide, Na 2 S(aq), are mixed. If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction. he following is a typical problem. Predict whether a precipitate will form when water solutions of silver nitrate, AgNO 3 (aq), and sodium sulfide, Na 2 S(aq), are mixed. If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction.
Symptoms include: itching, burning, redness and swelling. Treatment may include antibiotic or anti-allergy eye drops. Contact lens rewetting and eye surface lubrication. If your eyes sometimes feel dry wearing contact lenses, choose eye drops specifically intended for use with contacts. Other drops could discolour your contacts or temporarily change their fit.
To prevent eye infections if you wear contact lenses, you should do the following: 1  Keep your lenses clean and always follow the instructions on the cleaning solution label. 2  Wash your hand before changing your contacts. 3  Donât sleep with your contacts as this could cause eye boogers in the morning.
