The effect of strong base on water is to dramatically increase the concentration of OH^- ions and decrease the concentration of H_3O^+ ions. Water always contains at least small concentrations of …

Here's what I got. The problem wants you to use the base dissociation constant, K_b, of ammonia, "NH"_3, to determine the percent of ammonia molecules that ionize to produce ammonium cations, …

Question 1: K_ (sp)= 1.1 xx10^ (-11) Question 2: s= 4.9 xx10^ (-12)M Quest (1) determine the ksp for magnesium hydroxide Mg (OH)_2 where the molar solubility of Mg ...

where the combination ratio is 2:1 then 0,12 mol of nitric acid combine with 0,06 mol of #Ca (OH)_2#, but you have not this quantity, then #Ca (OH)_2# is the limitant reactant and 0,056 mol of it …

The inductive effect is the effect on electron density in one portion of a molecule caused by electron-withdrawing or electron-donating groups elsewhere in the molecule. In a covalent bond between two …

4.27 11.86 Ethanoic acid dissociates: sf (CH_3COOHrightleftharpoonsCH_3COO^ (-)+H^+) sf (K_a= ( [CH_3COO^-] [H^+])/ ( [CH_3COOH])=1.8xx10^ (-5)) These are equilibrium concentrations. To find …

The longer the alkyl chain attached to the hydroxyl head, usually the more basic the conjugate base is (and the less nucleophilic).

Since water is in excess, "67.7 g MgO" are needed to produce "98.0 g Mg(OH)"_2. Balanced equation "MgO(s) + H"_2"O(l)"rarr"Mg(OH)"_2("s")" Moles magnesium hydroxide Start with the given mass of …

The acid in excess is then titrated with N aOH (aq) of KNOWN concentration....we can thus get back to the concentration or molar quantity of M (OH)2...as it stands the question (and answer) are …

Basic. [H_3O^+]= [OH^-]=10^ {-7} M is a neutral solution. With higher [H_3O^+] you have [OH^-] and an acidic solution. With lower [H_3O^+] you get higher [OH^-] and you have a basic solution.
