Question #b8408 - Socratic
The thing to keep in mind here is that nitric acid is a strong acid, which means that it will ionize completely in aqueous solution to produce hydronium cations, H3O+, and nitrate anions, NO− 3. HNO3(aq) +H2O(l) → H3O+ (aq) + NO− 3(aq) Notice that every mole of nitric acid that is dissolved in water produces 1 mole of hydronium cations. This means that the concentration of hydronium ...
How many grams of \text {NH}_4\text {OH} do I need to make ... - Socratic
"6.3072 g" >>"Molarity" = "Moles of solute"/"Volume of solution (in litres)" "0.45 M" = "n"/"0.4 L" "n = 0.45 M × 0.4 L = 0.18 mol" You need "0.18 mol" of "NH"_4"OH" Molar mass of "NH"_4"OH" is "35.04 g/mol" Mass of solute = 0.18 cancel"mol" × "35.04 g"/cancel"mol" = "6.3072 g"
Question #18488 - Socratic
The degree of dissociation sf (alpha=0.0158) sf (K_b=2.51xx10^ (-6)color (white) (x)"mol/l") Triethyamine is a weak base and ionises: sf ( (CH_3)_3N+H_2Orightleftharpoons (CH_3)_3stackrel (+) (N)H+OH^-) For which: sf (K_b= ( [ (CH_3)_3stackrel (+) (N)H] [OH^ (-)])/ ( [ (CH_3)_3N])) Rearranging and taking -ve logs of both sides we get the ...
Can you give the IUPAC name for the following (CH_3)_3C-OH ... - Socratic
So this is a propanol derivative: "2-methylpropan-2-ol" For "isopropyl alcohol", H_3C-CH (OH)CH_3, the longest chain is again three carbons long, and C2 is substituted by -OH, so "propan-2-ol" I think this is right, and I haven't broken any arcane rule. Both names seem to be unambiguous.
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.
What is the product of the following reaction? 1)CH_3 OH - Socratic
These are ostensibly acid-base reactions.... For ammonium we could write.... NH_4^+ +HO^(-) rarr NH_3(aq) + H_2O(l) For methanol, the acid base reaction would proceed ...
Question #a721d - Socratic
pH = 1.61151 OH^- = 4.08797 * 10 ^-13M HF = 0.855538M H^+ = 0.024462M F^- = 0.024462M HF + H_2O = H_3O^+ + F^- We can find the concentration of H^+ or H_3O^+ by three ways One is by the ICE table (but this is a 5% rule) and the other is square root which is absolutely correct and the other is Ostwald's law of dillution Let's set up an ICE table. color (white) (mmmmmmmm)"HF" + "H"_2"O" ⇌ "H ...
Question #ccabf - Socratic
Because N aOH → N a+ + OH − and N i2+ + 2OH −→N i(OH)2 Total Mols of N aOH: 60mL ⋅ 0.45M ol/L = 27mM ol of N aOH (dont forget the m for milli=one thousandth) This will produce 27 2 = 13.5mM ol of N i(OH)2 Now you multiply this by the molecular mass number to get the weight in milligrams (divide by 1000 to get the grams). Nickel (II)hydroxide may be formed without or (more likely ...
Question #93f99 - Socratic
The molarity of the acid is 1.434. Start with the equation: 2HNO_ (3 (aq))+Ca (OH)_ (2 (aq))rarrCa (NO_3)_ (2 (aq))+2H_2O_ ( (l)) This tells us that 2 moles of HNO_3 ...
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...
