What will be the conjugate bases for the following Brönsted acids? HF, H₂SO₄, HCO₃⁻
निम्नलिखित ब्रॉन्स्टेड अम्लों के लिए संयुग्मी क्षारक क्या होंगे? HF, H₂SO₄, HCO₃⁻
  1. AF⁻, HSO₄⁻, CO₃²⁻F⁻, HSO₄⁻, CO₃²⁻
  2. BF⁻, H₂SO₃, CO₂F⁻, H₂SO₃, CO₂
  3. CF₂, H₂SO₄, CO₃²⁻F₂, H₂SO₄, CO₃²⁻
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं
Show answerHide answer

Correct answer: (A) F⁻, HSO₄⁻, CO₃²⁻F⁻, HSO₄⁻, CO₃²⁻

Explanation

A conjugate base is formed by removing a proton: HF → F⁻, H₂SO₄ → HSO₄⁻, and HCO₃⁻ → CO₃²⁻.संयुग्मी क्षारक प्रोटॉन हटाने पर बनता है: HF → F⁻, H₂SO₄ → HSO₄⁻ और HCO₃⁻ → CO₃²⁻।
