Baking soda and ammonia, common household cleaners, are a. [{Blank}] (acidic, basic, neutral) (2) What are the acid-base properties of the anion? the complete reaction of all H+ ions from the acid with all the OH- ions from the base. Classify NH4Cl as a strong acid, a strong base, a weak acid, or a weak base. The H+ ion is not an isolated ion, but interacts strongly with H2O to produce the ion, which has the formula H3O+. Share this. Lewis acid Classify an aqueous solution with OH- = 5.0 x 10-10 M as acidic, basic, or neutral. Therefore, a soluble acetate salt, such as sodium acetate will release acetate ions into the solution, which a few of these will interact with water, forming unionized acetic acid and the hydroxide ion.
