1. The problem statement, all variables and given/known data See below. 2. Relevant equations See below. 3. The attempt at a solution For 2-aminobutane, four solubility tests were done with the following solvents: NaOH NaHCO3 HCl H2O It was soluble in all of them. Is this correct? Is it soluble in H2O and NaOH because of its low molecular weight? Are these the correct equations for aminobutane’s results? CH3CH2CH(NH2)CH3 + HCl -> _________H _________| ______H-N-H ________| CH3CH2CHCH3 + Cl- where N is +. For NaOH, CH3CH2CH(NH2)CH3 + NaOH -> ?? I’m unsure at exactly how to express the solubility in an equation. In H2O, CH3CH2CH(NH2)CH3 + H2O -> _________H _________| ______H-N-H _________| (+ for N) CH3CH2CHCH3 + OH- ?? In NaHCO3, CH3CH2CH(NH2)CH3 + NaHCO3 -> ??? Again, I’m confused at expressing the experienced solubility. Any help is appreciated. Thanks.
