Answer:
The disadvantages of each of the given model of electron configuration have been mentioned below:
1). Dot Structures - They take up excess space as they do not display the electron distribution in orbitals.
2). Arrow and line diagrams make the counting of electrons and take up too much space.
3). Written Configurations do not display the electron distribution in orbitals and help in lose counting of electrons easily.
Answer:
The pKa of ethanol is higher than the pKa of water.
Explanation:
The Question above asked us to determine or Predict the relative pKa values of benzoic acid in water and in 95% ethanol.
So, there is going to be a higher pKa recorded for the ethanol than the pKa of water.
The reason is because the ka value will be larger for benzoic acid in water(that is the benzoic acid will act more as an acid here) and there will be less value for ka in 95% ethanol( that is the benzoic acid will act as less acid here than in water).
The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.
<h3>What is pH?</h3>
The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.
The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.
Therefore, the compound with a pH of 13.3 is basic.
