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.
Q. Why canât I use artificial tears with my contacts?A. Some solutions contain certain preservatives the lenses might absorb, resulting in a toxic reaction. Others may be too thick and cause blurriness if they build up on the lens. If you have dry eye, there are similar products for lens wearers that are safe to use..
