double-displacement reaction

Explanation:

We have the chemical reaction:

Na₂S (aq) + Cd(NO₃)₂ (aq) → CdS (s) + 2 NaNO₃ (aq)

where:

(aq) - aqueous

(s) - solid

This is a double-displacement reaction because the reactants exchange atoms or group of atoms between themselves to form the products. To drive the reaction to the right, one of the products is a precipitate.

Generally we can express the double-displacement reaction as following:

AB + CD → AC + BD

Which mixture would be best to use as a wash for removal of the alkylcatechol from skin exposed to poison ivy?water and baking s
Rudiy27

The question is incomplete. Here is hte complete question.

The components of poison ivy and poison oak that produce the characteristic itchy rash are cathecols substituted with long-chain alkyl groups. The image is attached.

If you were exposed to poison ivy, which of the treatments below would you apply to the affected area? Justify your choice.

(a) Wash the area with cold water.

(b) Wash the area with dilute vinegar or lemon juice.

(c) Wash the area with sopa and water.

(d) Wash the area with soap, water and baking soda (sodium bicarbonate)

Answer: (d) Wash the area with soap, water and baking soda.

Explanation: Alkyl is hydrophobic, which means it doesn't "mix" with water. To make it more soluble in water, soap helps to dissolve the chemical compound. As shown in the image, alkylcathecol is mildly alkaline. Baking soda is a salt that also helps dissolve it by ionizing with the -OH group, which makes it more soluble.

Although lemon juice and vinegar are acids, they are weak acids and so, won't have a strong effect on the alkylcathecol.

As said before, alkyl is hydrophobic, so plain water won't affect in any way the cathecol.
