For our purposes, an acid is a substance that increases the concentration of hydrogen ions (H + ^+ + start superscript, plus, end superscript) in a solution, usually by donating one of its hydrogen atoms through dissociation. Methylammonium comes from the weak base, methylamine so it can react to water in order to make hydrolysis. pH = 5 - 0.5 The Lewis structure of ammonia, NH3 , would be three hydrogen atoms bonded to a nitrogen atom in the middle, with a lone pair of electrons on top of the atom. F- + H2O --> HF + OH- (basic) Methylamine is a good nucleophile as it is an unhindered amine. What value of N does sulfuric acid have? - increases down a column as atomic radius increases so the atoms with the negative charge are LARGER in size so they can better distribute the negative charge (electrons more delocalized) which is more stable For example, the CH3NH3CN molecule present in urine is usually acidic because it is metabolized by the kidneys and other organs. 4.
