Include the units of mL in your answer. Solutions with a pH value less than 7 are acidic in nature and the pH value of basic solutions is greater than 7. Therefore the salt is acidic because of CH3NH3+, a Bronsted acid. The ions from KCl derive from a strong acid (HCl) and a strong base (KOH).Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.Although the K + ion derives from a strong base (KOH), the NO 2 ion derives from a weak acid (HNO 2). NH4C2H3O2c. For the next three problems, consider 1.0 L of a solution which is 0.55 M HF and 0.2 M NaF (Ka for HF = 7.2 x 10-4). An aqueous solution of KC2H3O2 will be basic.

Acid + Base Salt + Water HNO3(aq) + NaOH(aq) NaNO3(aq) + HOH(l) Strong acids and and bases ionize completely when they dissolve in water. This is the best answer based on feedback and ratings. These geometries have ideal bond angles of 109.5^@ in three dimensions, but the lone pair 'crunches' the atoms together a little, so the angles become less than 109.5^@. no: (C2H5)2NH2Cl It will have no sharp endpoint upon titration. You can also neutralize a base with an acid, but putting the acid in the . It is probably a bit alkaline in solution. cocl2 bond angle.
