Answer:
THE MOLARITY OF SULFURIC ACID SOLUTION IS 0.05 L
Explanation:
Ca Va = Cb Vb
Ca = ?
Va = 75.0mL = 0.075 L
Cb = 0.150 M
Vb = 25.0 mL = 0.025 L
Ca = CbVb/ Va
Ca = 0.150 * 0.025 / 0.075
Ca = 0.00375 / 0.075
Ca = 0.05 M
The molarity is 0.05 L

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⁺).
<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
