جب مضبوط اور کمزور تیزاب کا نمک پانی میں تحلیل ہوجاتا ہے تو ، نمک کی آئن ہائیڈروالیسس اور بنیادی حل کے نتائج سے گزرتی ہے۔ اس رد عمل کے لئے توازن مستقل کیا ہے؟
Explanation
  • When a salt of a strong base and a weak acid dissolves in water, the anion (from the weak acid) undergoes hydrolysis, forming a basic solution.
  • The equilibrium constant for this hydrolysis reaction is given by Kw/Ka, where:
    • Kw is the ionization constant of water (1 × 10⁻¹⁴ at 25°C).
    • Ka is the acid dissociation constant of the weak acid.
  • This equation shows how the strength of the weak acid affects the extent of hydrolysis and the resulting pH of the solution.
