technical-grade - containing small amounts of other chemicals, hence slightly impure; technical-grade sulfuric acid. technical grade. chemical science, chemistry - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions.
TA is defined as the amount of acid required to lower the pH of the sample to the point where all of the bicarbonate [HCO 3 - ] and carbonate [CO 3 -- ] could be converted to carbonic acid [H 2 CO 3 ]. This is called the carbonic acid equivalence point or the carbonic acid endpoint.he first is that there is no simply way to measure carbonate with a kit without doing a pH titration as an alkalinity test kit does. Second, corals may actually use bicarbonate instead of carbonate as their ultimate source of carbonate (which they split into H + and CO 3 --).
