Q: The product of H⁺ ions and OH⁻ ions in a strong alkali is
  • A.
  • B. 1
  • C. 10⁻¹
  • D. 10⁻ ¹⁴
Correct Answer: Option D - The base which have a very high ion content are called strong base. Na(OH) and K(OH) are strong bases. The concentration of OH is greater than 1 ×10⁻⁷ moles per liter due to alkali providing OH in an alkaline solution because the ionic product of water i.e the product of H and OH is constant and equal to 1 × 10⁻⁴ therefore, the concentration of H ion of alkaline solution is less than 1 × 10⁻⁷ so the pH value of alkaline solution is more than 7.
