Jun 1, 2016 · Here's a concept map that shows how to get from any of these to the other. [Really, the only things you need to remember are:

Apr 20, 2018 · In a hydroxide #(OH^-)# ion, we see that the total charge of the ion is #-1#. That means, the total sum of the oxidation numbers of the elements present in the ion totals out to be #-1#. The ion has one oxygen atom and one hydrogen atom. Hydrogen is less electronegative than oxygen, and so will possess its usual #+1# state.

May 8, 2014 · The pH + pOH = 14 The pOH = -log[OH-] The pH is measure of acidity of a solution whereas the pOH is a measure of basicity of a solution. The two expressions are opposites expressions. As the pH increases the pOH decreases and vice versa. Both values equal 14. To convert a concentration of into pH or pOH take the -log of molar concentration of the hydrogen ions or the molar concentration of the ...

Oct 4, 2015 · pH_"sol" = 8.07 You actually need the base dissociation constant, K_b, of the fluoride anion, "F"^(-), in order to be able to calculate the concentration of hydroxide ions it produces in aqueous solution. Since you did not provide that value, I will use the acid dissociaation constant, K_a, of hydrofluoric acid, "HF", to calculate the K_b of "F"^(-). The K_a of hydrofluoric acid is equal to 7. ...

May 26, 2017 · Where #OH^-) and CV^+# are the concentration of them in M. We know that the concentration of NaOH is 0.1M or the #OH^- # concentration is 0.1M as 1 mol of NaOH contributes 1 mole of #OH^-# because it is a strong base. The equation for dissociation in water #"NaOH" + "H"_2"O" rightleftharpoons "Na"^+ + "OH"^-# Plug in the new found variable

Jan 6, 2014 · The basic rules for naming alkenes are the same as those for the nomenclature of alkanes, except that we change the suffix to –ene. > Find the longest continuous chain of carbon atoms that contains the "C=C" double bond. If you have two ties for longest continuous chain and both chains contain a "C=C" double bond, then choose the chain with more substituents. Give the lowest possible number ...

Mar 22, 2016 · 2"OH"_text((aq])^(-) + "Cu"_text((aq])^(2+) -> "Cu"("OH")_text(2(s]) darr You're dealing with a double replacement reaction in which two soluble ionic compounds react to form an insoluble solid that precipitates out of the aqueous solution.

Jun 13, 2014 · There is quite a bit involved in this question. In general, the pH of an acid solution will be lower as the solution is more concentrated. For bases, the pH will be higher with more highly concentrated solutions. Here are some important relationships to remember: pH = -log[H+] pOH - log[OH-] pH + pOH = 14 [H+][OH-] = 1 x 10^-14 [H+] = 10^(-pH) [OH-] = 10^(-pOH) Here is a video which discusses ...

The general idea is that "poor" leaving groups have a strong nucleophilicity, or a strong "desire" to not bring its electrons with it and allow the bond to break.

Aug 11, 2016 · The first thing to do here is look up the values of the solubility product constant, #K_(sp)#, for lead(II) chloride, #"PbCl"_2#, and the formation constant, #K_f#, for the trihydroxoplumbate(II) complex ion, #"Pb"("OH")_3^(-)#
