Answer:
Explanation: the answer is A
The expression for the Ka for the given acid is:
Ka = [H2P2O7^2-] [H3O+] /[H3P2O7^2-]
<span>Ka is the acid dissociation constant or the acidity constant. It is a measure of the acid strength when in solution. It is an equilibrium constant for the dissociation of the acid.</span>
The isoelectric point<span> (</span>pI, pH(I),IEP<span>), is the pH at which a particular molecule carries no net electrical charge in the statistical mean.</span>
Answer:
b) The two pieces of tape will repel as both have obtained a static charge.
this is the right answer.
