The hydrogen ion concentration is 1 × 10-7. What is the ph of this solution?
Naya [18.7K]

Answer:

  • <em>The pH of the solution is </em><u><em>7</em></u>

Explanation:

<em>The pH</em> is a measure of the acidity of the solutions. It is defined as the negative logarithm of the molar concentration of hydrogen ions (H⁺).

  • pH = - log [H⁺]

<em>The hydrogen ion concentration of this solution is 1 × 10⁻⁷ M.</em>

Hence:

  • pH = - log (1 × 10⁻⁷) = - (-7) = 7

This pH corresponds to a neutral solution (neither acid nor alkaline).

You should remember this relation bwtween pH and acidity/alkaliinity:

  • Low pH (0.0 or close) corresponds to strong acids
  • HIgh pH (14.0 or close) corresponds to strong bases
  • Acids have pH between 0.0 and 7.0
  • Bases have pH between 7.0 and 14.0

soldier1979 [14.2K]

Answer: The correct answer is Option 1.

Explanation:

Control group is the group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.

We are given 4 groups which are being experimented for the flotation of an egg in water. As in Cup 1, there is no addition of salt and hence there is no change in the variables. So, this is set as a benchmark fro the cups which are further used in the experiment conducted.

Hence, the correct answer is Option 1.
