Basic: This molecule is basic because it contains a nitrogen atom which has a single negative charge.Acid: This molecule is acidic because the hydrogen atoms have a negative charge and the nitrogen atom has a positive charge. For example: 7*x^2. Determine whether each of the following salts will form a solution that is acidic, basic, or pH-neutral. CH3NH2 is a base in nature as when dissolved in an aqueous solution, it accepts the H+ ion from a water molecule and produces hydroxide ions (OH) that correspondingly show its basic nature. You can find the polarity of a compound by finding electronegativities (an atom's desire for an electron) of the atoms; Carbon has an electronegativity of 2.5, compared to Fluorine's A) Enter the the Ksp expression for the solid AB2 in terms of the molar solubility x.
