It is the aqueous solutionPROBLEM TO BE SOLVED: To provide a cold heat transportation medium containing tetra-n-butylammonium bromide hydrate having low corrosiveness, particularly low local corrosiveness.宗宮 賢治北川 尚男生越 英雅
For convenience, in most cases, we assume that the solution is at {eq}25^\circ C {/eq} so that the pH scale will revolve around pH = 7.00. At this temperature, pH 7.00 is the neutral pH. However, in real life, this is not always the case which is why for a more acc...
Water is a good solvent due to its polarity. The solvent properties of water are vital in biology, because many biochemical reactions take place only within aqueous solutions When an ionic or polar compound enters water, it is surrounded by water molecules. The relatively small size of water mo...
