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