WebNote: in the first four problems, I give the K a of the conjugate acid (for example, the ammonium ion in Example #1). The overall salt does not donate protons, the CH3NH3+ ion does (to form H3O+) when the salt is dissociated in water. An acid is a proton and a base is a proton. So CH3NH3Cl donated a proton to water which makes it an acid. Turns out, we require 62 mL or the CH3NH2 and 31 mL of the HCl for a total volume of The relevant Ka and Kb values are found in Tables 14.2 and14.3. In an acid/base reaction will there always be an acid and always be a base? pK_w &= pK_a + pK_b = 14\\ This is because it is made up of ammonia which is a very weak base and HClO which is a weak acid. The conjugate acid of HC3NH2 is CH3NH3^1+ Conjugate acid of Ch3NH2? I know for these problems, you can sometimes ignore parts of the solution for some reason. Is CH3NH3 a strong acid or base?

It will be hydrolyzed to produce an acidic solution. CH3NH2 is a stronger base as NH3. Because HCl is listed in Table 12.2 "Strong Acids and Bases", it is a strong acid. The water molecule acts as bases. Maybe you'll get different insights into ch3nh3cl acid or base here. LiF is obviously neutral, because it's a salt of very strong acid and very strong base. base conjugate acid NH 3 NH 4 + CO 3 2-HCO 3-HNO 3 H 2 NO 3 + Check for Understanding 6.2 1. b. NaOBr In result, leading HCl to dissociate more easily. Acid Base Theories Arrhenius Definition acid--donates a hydrogen ion (H+) in water base--donates a hydroxide ion in water (OH-) This theory was limited to substances with those "parts"; ammonia is a MAJOR exception!. 26. a. Being part of the list of strong acids doesnt give any indication of how dangerous or damaging an acid is though. The Kb for NH3 is about 10^-5 and Ka for HOCl is about 10^-8 I follow the rule of (H^+) = sqrt (KwKa/Kb) for weak acid/weak base salts. Ka for NH4+ is 1.00 x 10^-14 / 1.8 x 10^-5 = 5.6 x 10^-10. or neutral. Therefore, this compound will act as an acidic salt. If a substance has a pH lower than 7, it is an acid. MgI2 is Neutral I'll tell you the Acid or Base or Neutral list below. At the equivalence point, the moles of CH3NH2 equals the moles of HCl.
