Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Acetic acid (CH3COOH) is a weak acid. An aqueous solution of CH3NH3NO3 will be Group of answer choices A. basic, because of the hydrolysis of NO3 ions. Metal cations, Mn+ act as weak acids by acid hydrolysis to form M(OH)(n-1)+. Solutions of simple salts of metal ions can also be acidic, even though a metal ion cannot donate a proton directly to water to produce \(H_3O^+\). let's take NaF for example: Na+ would be NaOH as a base, which is strong. Will an aqueous solution of LiCN be acidic, basic, or neutral? What are the differences between a male and a hermaphrodite C. elegans?

If you are having trouble with Chemistry, Organic, Physics, Calculus, or Statistics, we got your back! For Free. , Explain. H3O+ is: {/eq} will be: A. basic, because of the hydrolysis of NO{eq}_3^- No packages or subscriptions, pay only for the time you need. Is ch3nh2 acid or base? Consider the molecules R-CH2OH and R-CH2CO2H where R is rest of the hydrocarbon molecule. What experience do you need to become a teacher? NH4CIO2 has a weak base and a strong acid, therefore it is a weakly acidic solution. ), So from eqn (2) above, we obtain Ka = (10-14)/(5.2 x 10-4) = 1.9 x 10-11. 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. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. How to do this pH calculation? | Wyzant Ask An Expert (See Exercise 175.

What happens with aqueous solutions of a salt such as ammonium acetate, where both the cation and the anion can react separately with water to produce an acid and a base, respectively? Kb (CH3NH2) = 5.2 x 10-4, Marita E. Favorite Answer. So yes, it is a weak acid (NH4+) and weak base (NO2-).
