Is there a passage I need to read for this because I don’t see it
NaHSO4 = Na+ + HSO4- Are the results in the first solution. The Na+ ion comes from a strong base NaOH and would rather stay in the solution state then couple with the OH- from the water. The HSO4- is from the strong acid H2SO4 and does not attract the H+ from the water. So the solution is neutral or pH = 7
<span>In the second case the Na+ as before comes from a strong base and doesn’t attract the OH- from the water to free the H+ remaining of the water molecule. However, the HCO3- is the ion from a weak acid and attracts the H+ of the water molecule leaving the OH- ion free to affect the pH of the water making it basic or above 7. </span>
<span>In both cases above the OH- and the H+ come from the dissolution of the H2O molecule by the equilibrium H2O = H+ + OH- . in the second case as the H+ attached to the HCO3- the equilibrium is shifted to the right producing more OH- giving the solution its basic characteristics. </span>
<span>Both word mean the same thing. Ions are formed and a solution is created.
Hope this helped.

Answer:
To form the past perfect tense you use the past tense of the verb "to have," which is had, and add it to the past participle of the main verb.
Explanation:
For example: subject + had + past participle = past perfect tense. Some examples of the past perfect tense can be seen in the following sentences: Had met: She had met him before the party.
