  • The third category of German verb is mixed verbs, which are a mix between the other two categories (strong and weak). In other words, a mixed verb will have a spelling change in the past tense (typically, a vowel change like strong verbs) with normal verb endings (like weak verbs). •Mar 14, 2018 · A strong acid with a dissociation constant of 10 7 has a pKa of -7, while a weak acid with a dissociation constant of 10-12 has a pKa of 12. Besides being easier to work with, pKa values have an inverse relationship to acid strength. In other words, a low pKa indicates a strong acid and vice versa.

    In the second set, the vowel sound changes, and -d is added. A verb which forms its past tense by adding -ed, -d or -t to the present tense, either with or without a change in the vowel sound, is called a weak verb.

Na2S is a salt of a weak acid (H2S) and a strong base (NaOH). An aqueous solution of such a salt is distinctly basic owing to the presence of additional OH- ions that are produced by hydrolysis of the anion.

Oct 12, 2008 · A is strong, B is weak, C is intermediate. A is strong because it is an ionic bond and completely disassociates in aqueous solutions in water. Ionic bonds are badass like this. B is weak, it is covalent and will not disassociate in water. Think of sugar, in this case B is a carbohydrate...if you put that in water, it will not work. C is an ...

There are very few strong bases (see Table 12.2 “Strong Acids and Bases”); any base not listed is a weak base. All strong bases are OH – compounds. So a base based on some other mechanism, such as NH 3 (which does not contain OH − ions as part of its formula), will be a weak base.

Jan 20, 2011 · NaNO2 dissociates almost completely: NaNO2 (aq) --> Na+ (aq) + NO2- (aq) The resulting ions could react with water: Na+ + 2 H2O <--> NaOH (aq) + H3O+ (aq) Since NaOH is a strong base, this reaction doesn't occur appreciably. NO2- (aq) + H2O <--> HNO2 (aq) + OH- (aq) The results of this reaction do appear because HNO2 is a weak acid.
