A mixture of compounds containing diethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as
follows: Step 1: Concentrated HCl is added followed by draining the aqueous layer. Step 2: Dilute NaOH is added to the organic layer followed by draining the aqueous layer. Step 3: Concentrated NaOH is added to the organic layer followed by draining the aqueous layer. Which compound would you expect to be extracted into the aqueous layer after the addition of dilute NaOH, step 2?
In the first step, since we are adding a concentrated acid,<u> it will react with the bases present in the mixture (diethylamine and ammonia) </u><u>forming salts</u><u>, </u><u>which are soluble in water</u>. Therefore, after draining the aqueous layer, we will have phenol and acetic acid left in the organic layer.
In the second step, we are adding a diluted base, so it will react with a strong acid. This compound is acetic acid, and its salt will be present in the aqueous layer. Phenol will be left on the organic layer.
The hydroponic garden is different than a normal garden because the plants are required to find more components in the soil. One more difference among hydroponic gardening or ordinary gardening is that hydroponics could be complex. fertilizer for hydroponic growing are usually in more immaculate structure than are regular fertilizer.
Chemical equations have reactants to its left and products to its right. It is natural that number of atoms of each element in the reactants must be balanced with the number of atoms of those elements in the products also. This is called balancing of the chemical equation.
