Question #6cd6a - Socratic
For neutralization mol of H+ ions of acid = mol of OH- ions of base So first you need to know the H+ of 10ml of 0.1 M HCl The number H^+ ions in the solution is the concentration of HCl because strong acids dissociate completely thus producing "1mole of H+"/"1mole of acid." This is only applicable to strong acids. The same is the case with strong base but instead of H^+ they produce strong ...

What are the acids in this equilibri reaction? #CN^- + H_2O ... - Socratic
The acids in the given reaction are hydrogen cyanide and water. An acid is a proton donor. Cyanide anion is a reasonable base, and will deprotonate water to give hydrogen cyanide and hydroxide anion: C-=N^(-) +H_2O rightleftharpoons HC-=N+HO^- What would be the hazards involved in this reaction?

What is the "pH" of a solution of magnesium hydroxide given ... - Socratic
"pH" = 10.52 In order to find the pH of a solution, you must determine the concentration of hydronium ions, "H"_3"O"^(+), either directly or indirectly. When you're dealing with a Bronsted - Lowry acid, you will be solving for the concentration of hydronium ions directly. When you're dealing with a Bronsted - Lowry base, like you are here, you will be solving for the concentration of hydronium ...

Question #947ff - Socratic
Barium hydroxide, #"Ba"("OH")_2#, is a strong base, which means that it dissociates completely to form barium cations and hydroxide anions -- keep in mind that barium hydroxide is not very soluble, but the amount that dissolves does so completely.

What is the value of ΔG°cell? - Socratic
They have a cadmium anode, which is oxidized to Cd(OH)2(s) in a basic background electrolyte of concentrated OH–, and a cathode half-reaction in which NiO(OH)(s) is reduced to Ni(OH)2(s). Cd(OH)2 +2e^- -> Cd +2OH- E^o red = -0.403V

Question #11c1a + Example - Socratic
Well, that would be a neutralization reaction. If you're asking what I think you're asking, then you're dealing with a neutralization reaction. A neutralization reaction is said to take place when a base reacts with an acid to form salt and water. In your case, sulfuric acid, "H"_2"SO"_4, a strong acid, will react with magnesium hydroxide, "Mg"("OH")_2, a weak base, to form aqueous magnesium ...

Question #410dd - Socratic
A) 2 The van't Hoff factor, i, tells you the ratio that exists between the number of moles of solute dissolved in water and the number of moles of particles of solute produced in solution. i = "what you get in solution"/"what you dissolve to make the solution" Potassium hydroxide, "KOH", is a soluble ionic compound, which means that it dissociates completely to form potassium cations and ...

Which of the following is a redox reaction? - Socratic
You need to learn something early on in chemistry, maybe in life. It's not about how little work you can do. If you work hard now, this will be easier in an exam setting. I worked hard at this and this is trivial to me, now—I can do this in my head. Moving on! In reduction-oxidation reactions, one species is reduced and another is oxidized. Usually this is straightforward, having calculated ...

What is the oxidation number of iron in goethite? | Socratic
The oxidation number is +3. > Goethite is a dark and usually uninteresting mineral. Its chemical formula is "FeO(OH)", although it often contains small amounts of other metals such as manganese. We can use the rules for oxidation numbers to determine the oxidation number of "Fe". The essential rules for this problem are: The oxidation number of oxygen in a compound is almost always -2. The sum ...

When adding base to a weak acid, does the concentration of
The increase in wk acid beyond an equivalent reaction mixture of acid and base is 'insignificant' and pH increases should be assumed to be exclusively due to additional #(OH^_)# titrant. Explanation: Consider the reaction of one equivalent of acid and one equivalent of base.
