solution of silver chloride at constant temperature: AgCl(s) ↔ Ag+(aq) + Cl-(aq) As NaCl(s) is dissolved in the solution, the concentration of the Ag+ ions in the solution 1. decreases, and the concentration of Cl- ions increases 2. decreases, and the concentration of Cl- ions remains the same 3. increases, and the concentration of Cl- ions increases 4. increases, and the concentration of Cl- ions remains the same

Answers

If in the silver chloride solution we add NaCl then concentration of silver ions decreases, and the concentration of Chloride ions increases.

What is equilibrium law?

According to this law, when any external stress is applied in the equilibrium state then the reaction will shift on those side where the stress will reduces.

If in the silver chloride solutions then in the solution silver and chloride ions are present, and then when we add sodium chloride to that solution then it also dissociates into sodium and chloride ions. Then as a result of which concentration of chloride ions increases and to maintain the change equilibrium will shift towards the reactant side as a result of which concentration of silver ion decreases.

Hence, concentration of silver ions decreases, and the concentration of Chloride ions increases.

As a matter of fact, NaCl(s), when dissolves in water, dissociates into ion Na+ and Cl-.

There is water in the silver chloride solution. Therefore, when being added to the solution, NaCl dissociates into Na+ and Cl-, which makes the concentration of Cl- in the solution increase.

According to Le Chatelier's Principle, when [Cl-] increases, the chemical equation seems to shift in a way that could make more AgCl. Therefore, Ag+ has to react with Cl-, which makes [Ag+] decrease.

The correct answer is (1).

How to figure out if compounds are electrolytes

Answers

An electrolyte is a compound that dissolved into its ions when placed into a solvent such as water (the ions can carry an electric charge). An easy way to test whether something is an electrolyte is by placing the substance in Deionized water and testing if the resulting solution can carry a current. If the resulting solution can carry a current, the substance is an electrolyte. I hope this helps. Let me know if anything is unclear.

The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 L?

Answers

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

P2 = P1V1/V2

P2 = 1 atm x 450 mL / 2000 mL

P2 = 0.225 atm
