- Question #71ce2 - Socratic
H^+ + OH^--> H_2O when the acid was added to the resulting solution The H^+ and OH^- react in a 1:1 ratio This tells us that the number of moles of H^+ used will be equal to the number of OH^- moles in solution Likewise, 2 moles of lithium produces 2 moles of OH^- This is also a 1:1 ratio
- Question #fcf5e - Socratic
OH− (aq) + H3O+ (aq) → 2H2O(l) so you can say that when you mix these two solutions, the hydronium cations present in the hydrochloric acid solution will be the limiting reagent, i e they will be completely consumed by the reaction
- Question #6f539 + Example - Socratic
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 both OH^- (hydroxide) and H_3O^+ (hydronium) ions This is because water can react with itself in a self-ionization reaction: 2 H_2O harr H_3O^+ + OH^- At equilibrium, which is attained quickly for
- Question #9f499 - Socratic
Explanation: Your starting point here is the pH of the solution More specifically, you need to use the given pH to determine the concentration of hydroxide anions, #"OH"^ (-)#, present in the saturated solution
- Question #645c9 - Socratic
How about these? > (a) With "HCN" The "HCN" adds across the α "C=O" group to form a cyanohydrin underbrace ("CH"_3"COCOOH")_color (red) ("pyruvic acid") + "HCN" →
- Question #e7848 - Socratic
Similarly, OH^- becomes H_2O, indicating a gain of a H^+ ion So, you can say that NH_4^+ is the acid, and OH^- is the base Conjugates are basically the "other" term For every acid, you have a conjugate base (that no longer has that extra H^+ ion), and for every base, you have a conjugate acid (that has an extra H^+ ion)
- Question #845d9 + Example - Socratic
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 atoms of unequal electronegativity, the more electronegative atom draws electron density towards itself This causes the δ⁺ and δ⁻ charges of the bond dipole "H"^(δ+)-"Cl"^(δ-) If the
- Calculating the concentration of excess HCL in E - Socratic
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 hypothetical
