Akey strategy in sustainable farming is integrated pest management (ipm) which is the combination of different techniques to create an effective pest control system. not all pests need to be eliminated; monitoring and prevention of pest is also an integral part of ipm. aquafarming is the farming of aquatic species such as fish, crustaceans, mollusks, and aquatic plants and often uses sustainable farming techniques. the limits of a certain type of aquafarming pest during the farming of catfish might be expressed as a 10 ug/l, not to exceed 2 days, and not to recur more than once every 6 months. what does 6 months represent in the management of pest limits for the above example? a) average b) duration c) frequency d) magnitude

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely. analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
