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.
Eye redness is not normal. If over-the-counter products are not effective, it may be time to see your eye doctor. Prescription eye drops are prescribed for various reasons. Anti-allergy eye drops, such as Patanol, Livostin, Alomide, and Cromolyn relieve itchy, red, watery eyes by preventing the release of histamines.Anti-allergy eye drops are the most common eye drops prescribed.or people suffering from allergies, an eye drop containing an antihistamine is best. For people with dry eyes, lubricating eye drops are helpful. Some eye drops require a doctorâs prescription, so if you are not able to find an eye drop for your particular discomfort, it is a good idea to ask your doctor.
