Question

4. In the covalent compound HCI, H-CI, or H:CI, which element has the greater electronegativity? 5. The covalent bond between H and CI is pH The shared electrons should be closer to 1s(polar/nonpolar). The acid or basic strength of a solution may be expressed in terms of a number called the pH of that solution. The pH scale expresses the concentration of hydrogen ions (and hydroxide ions) in solution. The pH range is from 0 to 14, with a pH of 7 indicating a neutral solution. A pH below 7 indicates an acid solution. A pH above 7 indicates a base solution. 1. a. A p? of 3 indicates an) ucaie solution. ution. b. A pH of 7 indicates a(n) c. A pH of 9 indicates a(n) solution. 2. Whieh of the following pt vales indicates a solution containing a strong acid? b)7 e) 1 d) 6 3.

What is the [H'] of a 0.01 M solution? What is the pH? 2. Is the hydrogen ion concentration of a pH 3 solution higher or lower than that of a solution with a pH of 6? 3. If one solution has 100 times as many hydrogen ions as another solution, what is the difference, in pH units, between the two solutions? 4. If solution A contains 1 X 10 M H' ions and solution B contains 1 X 10* M H ions, which solution contains more H ions?

Explanation / Answer

because it has 7 electrons in its outermost orbit so it will accept one electron to complete its shell and hence becomes electronegative.

and we know that pH = -log [H+]

=-log [10-2] = 2
