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.
If you develop red eyes while wearing contact lenses, consider it a warning sign. While a contact lens may seem small and harmless, you must keep in mind that it is a foreign body resting on the surface of your eye. If your eyes turn red while wearing your contacts, it may mean you are simply overwearing them. However, there are many conditions that can cause increased eye redness while wearing contacts. Below are the top seven reasons why your contacts may be causing red eyes.
