Answer:
The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. ... In general, substances expand or contract when their temperature changes, with expansion or contraction occurring in all directions.
Hello!
When HI is added, the buffer reacts in the following way:
1) Neutralizing of the Acid:
HI + NH₄OH → NH₄I + H₂O
2) Dissociation of the salt of a weak acid:
NH₄I → NH₄⁺(aq) + I⁻ (aq)
3) Dissociation of a weak acid to form H₃O⁺ (very little):
NH₄⁺ + H₂O ⇄ NH₃ + H₃O⁺
This series of reactions show how the adding of a strong Acid can be neutralized by the buffer, releasing instead very little amounts of Hydronium ions.
Have a nice day!
Answer:
2
Explanation:
the pH of the strong acid solution will be
pH = -log[H+] = -log[0.01] = 2
Ok well whats the questions
