Algebra 2 Assignment Factor Each Completely Kuta Software, conjugate of acid, Q:Which of the following acids would be able to neutralize the most base? Acid. Again, the cations (\(K^+\) and \(Na^+\)) have essentially no acidic character, but the anions (\(CN^\) and \(CH_3CO_2^\)) are weak bases that can react with water because they are the conjugate bases of the weak acids \(HCN\) and acetic acid, respectively and they have Ka > 1 x 10-14. NaClO2(aq), A:Since we know that when sodium chlorite react with sulfuric acid to produce sodium sulfate, chloric, Q:Write products of the following acid-base reaction. Since CH3NH3NO3 is an acid, you convert the 5.2 x 10-4 through dividing by 1.0 x 10-14 to get ka Then you use the normal calculations and multiply ka If a substance has a pH lower than 7, it is an acid. The Ka for NH4+ can be found by Kw/(Kb for NH3) and the Kb for NO2- can be found by Kw/(Ka for HNO2). Why? When the pH values were measured, the solutions showed different pH values: It is formed from the neutralization of strong acid, namely Nitric acid (HNO 3) with a weak base, namely Ammonium hydroxide (NH 4 OH).
