Bonds that usually dissociate in water to form electrolytes are ____

What is the charge on an atom with 10 protons and 8 electrons?

maks197457 [2]

Hi,
The answer is +2, since there are 10 positive charges (protons) and 8 negative charges (electrons), so 10(+1) + 8(-1)= +10 -8= +2.

If my answer was not clear enough or you’d like further explanation please let me know.
Hope this helps!

Identify each of the following compounds as: (a) a nonelectrolyte: lactose (c12h22o11) potassium chloride (kcl) lactic acid (hc3

Nonelectrolytes are compounds that do not tend to get ionize in all solution. As a result, solutions which contains nonelectrolytes will not conduct electricity.

Ionic compounds dissolve in water and break into the constituent ions through the process called ionization. Now These electrolyte solutions can either be acids, or bases, or salts.

If the process of ionization produces a large no. of ions in the solution, it is a strong electrolyte. On the other hand, if it produces only a few ions, the solution is a weak electrolyte,

Potassium chloride (KCL) is a strong electrolyte,

Lactic acid (HC3H503) is a weak electrolyte,

Whereas, Ethanol (C3H7OH) is a non electrolyte,

Dimethylamine (CH3)2NH is a weak electrolyte,

Sodium hydroxide(NaOH) is a strong electrolyte.

Determination of Vitamin C Concentration by Redox Titration Pre-laboratory Questions 1. A solution is prepared by dissolving 2.0

Ierofanga [76]

Answer:

M = 0.011

Half reactions for reduction and oxidation:

oxidation:

HC12H6Cl2O2N + NH+ +2e- = HC12H8Cl2O2N

reduction:

C6H8O6 = C6H6O6 + 2H+ + 2e-

Explanation:

Molarity of the ascorbic acid solution:

Ascorbic acid molar mass = 173.12 g/mol

Then you have to find the mols:

mol = 2g/176,12 =0.011 mol Ascorbic acid.

Use the molarity equation:

Molarity (M) = 0.011 mol / 1 L = 0.011 M

Reactions for the reduction of DCPIP by ascorbic acid:

These reactions have to be balanced by the oxide reduction method.

Because it involves the transfer of electrons from ascorbic acid to the DCPIP.

Remember: when is happens a reduction, also happens oxidation.

To see the reactions watch the images attached.

The first one has the calculus for the molarity of the ascorbic acid solution.

The second one has the reactions for the reduction and oxidation of the compounds.
