The information from this discipline will help environmental scientists understand why there is a decrease in fish in the ocean. The reasons can vary from over fishing to decline in the reproduction of fishes due to climate change.
Answer :The corrected answer is given below;
Weak bases react with <u>water</u> to form the hydroxide ion and the conjugate <u>acid</u> of the base. Concentration in solution does not affect whether an acid or a base is <u>strong </u>or weak.
The strength of an acid or a base is determined by the <u>dissociation constant</u> of the substance in solution.
The acid dissociation constant, <u>Ka</u>, is a quantitative measure of acid strength. A strong acid has a much <u>higher</u> Ka than a weak acid. The Ka of an acid is determined from measured <u>titration</u> values.
Hydrochloric acid and sulfuric acid are <u>completely</u> ionized in solution and are <u>strong</u> acids. Ethanoic acid, which is only about 1 percent ionized, is a <u>weak</u> acid. Magnesium hydroxide and calcium hydroxide are strong <u>base</u>.
