Do all titrations of a strong base with a strong acid have the same ph at the equivalence point?
Luba_88 [7]

Answer:

  • <u>Yes,</u> <em>all titrations of a strong base with a strong acid have the same pH at the equivalence point.</em>

       This <u>pH is 7.</u>

Explanation:

<em>Strong acids</em> and <em>strong bases</em> ionize completely in aqueous solutions. The ionization of strong acids produce hydronium ions, H₃O⁺, and the ionization of strong bases produce hydroxide ions, OH⁻.

Since the ionization of strong acids and bases progress until completion, there is not reverse reaction.

The definition of pH is pH = - log [H₃O⁺]. Acids have low pH (below 7, and greater than 0) and bases have high pH (above 7 and less than 14). Neutral solutions have pH = 7.

Acid-base titrations are a method to determine the concentration of an acid from the known concentration of a base, or the concentraion of a base from the known concentration of an acid.

The<em> equivalence point</em> of the titration is the point at which the the number of moles of hydronium ions and hydroxide ions are equal.

Then, at that point, the hydronium and hydroxide ions will be in the stoichiometric proportion to form a neutral solution, i.e. the pH of the solution wiill be 7.

What is the difference in atomic structure between Lead-205 and Lead-208?
Nataly_w [17]

Answer:

  the number of neutrons in the nucleus

Explanation:

The mass number 205 is the total number of protons and neutrons in the nucleus. Lead has 82 protons, so a mass number of 205 indicates a nucleus with 123 neutrons.

Similarly, the mass number 208 indicates a lead nucleus with 126 neutrons.

The difference in atomic structure is the difference in the number of neutrons in the nucleus.
