A solution has a [H3O+] of 1 × 10−3 M. What is the [OH−] of the solution?
Marina CMI [18]

Answer:

D. 1x10⁻¹¹ M

Explanation:

For any given aqueous solution the<em> following formula</em> is true:

1x10⁻¹⁴ = [H₃O⁺] * [OH⁻]

1x10⁻¹⁴ is the ion-product constant of water, <em>Kw</em>.

We <u>input the given value of [H₃O⁺]</u>:

1x10⁻¹⁴ = 1x10⁻³ * [OH⁻]

And <u>solve for [OH⁻]</u>:

[OH⁻] = 1x10⁻¹¹ M

Thus the correct answer is option D. 1x10⁻¹¹ M.

Sometimes when performing a crystallization, one solvent alone will not work and you have to use a solvent-pair. Will the solven
love history [14]

For the crystallization purpose the combination of solvent process is known to be an effective process. But the solvent pair one have to choose crucially. The solvent which is completely in soluble into the other solvent can not work as a good solvent pair for the crystallization. The crystallization of any compound by the solvent pair process is depend upon the slow diffusion of a less polar solvent to the polar solvent or vice-versa.

If a compound is soluble in a polar solvent the slow diffusion of relatively low polar solvent will make crystal of the compound. But anyhow the solvents which are completely not immiscible to each other will not work for the purpose. Thus diethyl ether and water solvent pair can not be used for the crystallization process.

Select the correct answer. which substance in this redox reaction is the oxidizing agent? cu 2agno3 → 2ag cu(no3)2 a. n b. agno3
lana66690 [7]

AgNO₃ will act as the oxidising agent.

<h3><u>For the given chemical equation:</u></h3>

Cu + 2AgNO₃ →  2Ag + Cu(NO₃)₂

Half reactions for the given chemical reaction:

<u>Reducing agent:</u>

Cu → Cu²⁺ + 2e⁻

Copper is a reducing agent because it is losing 2 electrons, which causes an oxidation process.

<u>Oxidising Agent</u>:

Ag⁺ + e⁻ → Ag

The silver ion undergoes a reduction process and is regarded as an oxidizing agent since it is acquiring one electron per atom.

Hence, AgNO₃ is considered as an oxidizing agent and therefore the correct answer is Option B.

<h3><u>Oxidising and Reducing agents</u></h3>
  • An oxidizing agent is a substance that reduces itself after oxidizing another material. It passes through a reduction process in which it obtains electrons and the substance's oxidation state is decreased.
  • A reducing agent is a chemical that oxidizes after reducing another material. It passes through an oxidation process in which it loses electrons and the substance's oxidation state increases.
