<span> Scientific reasoning consists of observation, forming a workable hypothesis and arriving at a conclusion. Almost without exception major scientific discoveries were made and are being made today based on these same precepts. It only seems logical when an individual makes a difficult decision he/she will apply all or part of these processes. Let;s say that you want to make someone;s acquaintance to possibly become serious. Certainly, you would begin by quietly observing them, then you might make a hypothesis, "This person might make a good companion for me." Then in your conclusion you would test your hypothesis and proceed as directed. THis may be a bit simplistic, and I hope that it helps.</span>

Phosphoric acid has 3 pka values, which are 2.1, 6.9, and 12.4. draw the protonated form of phosphoric acid associated with the

Margaret [11]

As mentioned above, phosphoric acid has 3 pKa values, and after 3 ionization it gives 3 types of ions at different pKa values:

H₃PO₄(aq) + H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq) pKₐ₁
<span>

</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq) pKₐ₂

HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq) pKₐ₃

At the highest pKa value (12.4) of phosphoric acid, the last OH group will lose its hydrogen. On the picture I attached, it is shown required protonated form of phosphoric acid before reaction whose pKa value is 12.4.

Sladkaya [172]

Sonia observed that the two balloons repelled each other. This is because both balloons acquired the same charge when she rubbed them with the piece of wool, and like charges repel each other.
