From ChemPRIME. Jump to: navigation, search. First NaOH is a base, so speaking of an acid dissociation constant would be unusual, but since Ka x Kb = Kw, it wouldn't be impossible. * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. Trending Questions. 0 0. Tables of Ka and and Kb values. You just assume it dissociates completely. il y a 5 ans. HCl and NaOH are strong acid and strong base respectively and their titration curves are similar (shape of curve) in different concentrations. Strong bases completely dissociate in aq solution (Kb > 1, pKb < 1). HCl and NaOH reacts in 1:1 ratio (in same amount). LiOH is a strong base, therefore it is 100% dissociated. Both reactants and products are in aqueous state. The values of the constant is defined by the equation: The Base Constants for Some Bases at 25°C. 0 0. Generally you don't have to worry about it. Ask Question + 100. kb = [Na+][OH-]/[NaOH] Just about all of the NaOH dissociates so its concentration is extremely low. Anonyme. An equilibrium constant requires that the base (or acid) is not 100% dissociated and that there is an actual equilibrium in solution. NaOH + HCl = NaCl + H 2 O. It will have no Kb value because of that. Trending Questions. So I … NaOH: 1: 39.99710928: H 2 O: 1: 18.01528: NaBrO: 1: 118.89316928: Units: molar mass - g/mol, weight - g. Please tell about this free chemistry software to your friends! HCl is a strong acid, so because of its complete dissociation you don't need a Ka value for that one. Get your answers by asking now. Join. Group I metal hydroxides (LiOH, NaOH, etc.) Direct link to this balanced equation: Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. Important factors and equations of HCl + NaOH reaction and its titration curve. Second, Ka and Kb are used to describe weak electrolytes. Above is a table of K a values which define the extent to which an acid will donate its proton to water. Group II metal hydroxides (Mg(OH)2, Ba(OH)2, etc.) Conjugate acids (cations) of strong bases are ineffective bases. The pKa values for organic acids can be found in Appendix II of Bruice 5th Ed. So kb is very large. Source(s) : give kb naoh: NaOH is a strong base, so the denominator in the Ka expression would be 0 (no undissociated particles,) making the expression undefined.
