Ans 1 has been correctly answered , let me help you out with the next one.
Since hexyl amine is not very polar , it is not very soluble in water ( 12g/L) , due to its hydrophobic alkyl chain. The molecule is basic with pka~10 , so it ionises in the presence of acid such as 10% HCl solution , and its solubility increases .
The reaction is given as :
CH3(CH2)4CH2NH2 + HCl = CH3(CH2)4CH2NH3+Cl-
