It is easily soluble in water and is mainly used in the production of fertilizers. Explain. Solutions of salts that are products of weak acid-weak base reactions can be neutral, acidic, or basic, depending on the relative magnitude of the Ka of the weak acid and . I've tried submitting the ones that are insoluble in water and it was wrong. The subscripts don't matter, what matters is the strength of the conjugate acids and bases that are present. Predict whether the following solutions are acidic, basic, or nearly neutral: a) NaBr b) K2SO3 c) NH4NO2 d) Cr(NO3)3. a) neutral b) basic c) acidic d) acidic. The salt is made of ammonium ion and nitrite ion. It is made of a weak base ammonia and a strong base HCl, and therefore, the solution is going to be acidic. Simply so, is kno2 acidic basic or neutral? The pH scale measures how acidic or basic a substance is.

The pH of the solution was found to be 5.25. Expert Answer 100% (2 ratings) This is not a neutral salt "because it is formed from a weak acid and a weak base". An acid, Citric acid to be precise. It is made from the neutralization reaction of strong acid, namely Nitric acid (HNO 3 ), and weak base, namely ammonium hydroxide (NH 4 OH). * Typically ranges from 0 to 14. The (H^+) of solutions of salts that are salts of weak acids AND weak bases = sqrt (KwKa/Kb). Salt hydrolysis is a reaction of salt and water, producing an . Basic NH3 (or maybe NH4OH makes more sense as a starting material) reacted with acidic HNO2 to form a salt made of a weak conjugate acid cation and a weak conjugate base NO2-. KClO4 dissociates into K+ ions (neutral metal cation) and ClO4 ClO 4 ions (the conjugate base of a strong acid and therefore neutral). pH= 10.792. In chemistry, bases are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor, and/or contain completely or partially .
