Base. Because CH3NH2 is a weak base (kb = 5.0 * 10-4), the salt, CH3NH3NO3, serves as a weak acid. Which of the following statements is correct about the reaction below? Salts of hypoiodite ion behave as a weak base, undergoing hydrolysis in water according to the equation: [H+] at equilibrium is equal to x, so plugging the above values into the Ka expression from eqn (1) and using the Ka value you got from eqn (2), you have: x << 0.80M (use the 5% rule, that is if x is less than 5% of the initial concentration, you can ignore it to simplify the calculation. A base is defined as a proton acceptor or lone pair donor. The cation will be the acid, and the anion will be the base and will form either form a hydronium ion or a hydroxide ion depending on which ion reacts more readily with the water. The chloride ion has no effect on the acidity of the . Question = Is ICl3polar or nonpolar ? Acid = H2SO4 The methylammonium cation CH3NH3+ is similar to the ammonium (NH4+) which is somewhat acidic due to it being the conjugate acid of a weak base (NH3). CH3NH2 is a weak base (Kb = 5.0 * 10-4) and so the salt, CH3NH3NO3, acts as a weak acid. {/eq} ions. Match each of the solutions with the measured pH values. So yes, it is a weak acid (NH4+) and weak base (NO2-). Strong base + strong acid = neutral salt Strong base + weak acid = basic salt Weak base + strong acid = acidic salt Weak base + weak acid = neutral salt [H3O+] = 7.5 10 . b) it is only slightly soluble in water.

The compound methylamine, CH_3NH_2, is a weak base when dissolved in water. Question = Is AsH3polar or nonpolar ? Both \(HCN\) and acetic acid are stronger acids than water, and hydroxide is a stronger base than either acetate or cyanide, so in both cases, the equilibrium lies to the left. It is because barium bromide reacts promptly with air. ), So from eqn (2) above, we obtain Ka = (10-14)/(5.2 x 10-4) = 1.9 x 10-11. C. NaOH solution HAsO42-(aq)+ H2O (liq) AsO43-(aq) + H3O+(aq) As you already know, the chloride ion is such a weak base that it does not react with water. , Sort these compounds into the proper categories. Second, the positive charge on the \(Al^{3+}\) ion attracts electron density from the oxygen atoms of the water molecules, which decreases the electron density in the \(\ce{OH}\) bonds, as shown in part (b) in Figure \(\PageIndex{1}\).
