Question

3. A solution containing which one of the following pairs of substances will be a buffer solution? A) Nal, HI B) KBr, HB C) NaCl, HCI D) NaF, HF E) NaNO3, HNO3

Answer 1

Acidic Buffer i mixture - mixture Basic Buffer of weak Aeid and its conjugate base CHA +A) of weak Base and its conjugate acid (B + HBP) Nal – Scelt A) NAI ,HI HI → strong Acid / no Butter B) KBr , HBr → no Buffer KBr- HBr salt strong Acid c) Nach, HCl Nacht salt Hely strong Acid I no Butter d) Naf, Hf so this NaNO3, KND - Naf Nato conjugute buse HF Weak Acid pair will be a buffer solution NONO, salt Aid I no Butter KNO3 → strong Acid J e) so Buffer solution will be [(d) Naf , HF Ane.
