Answer:

a. True

Explanation:

Yes, the titration curve can determine or can reveal the pKa value of a weak acid.

Titration is a scientific method to estimate the dissolved substance concentration, known as the titrand, in a known volume when it reacts with another chemical substance of known volume as well as concentration. The other substance is known as Titrant.

When a weak acid like acetic acid is titrated to a very strong base such as NaOH, the titration curve is obtained and the pH value is noted. But the titration curve of any weak acid shows a characteristic shape. At the end of titration, the acetic acid will convert into acetate ions.

pKa is the negative logarithm of the Ka of the acid. pKa is the pH of the acid  where the concentration of the weak acid as well as the conjugate base is in equimolar concentration.

Serggg [28]

Answer:

The correct answer is a. chemical bond. See the explanation below, please.

Explanation:

The resulting electrostatic interaction is called ionic bond between ions of opposite charge (one negative and one positive). This allows the attraction between both charges, constituting a chemical compound. Eg the Sodium (Na +) ion combines with the Chlorine (Cl-) ion forming Nacl (sodium chloride, known as table salt).
