The following aqueous solutions represents good buffer systems:
- 0.22 M acetic acid + 0.15 M potassium acetate
- 0.29 M ammonium nitrate + 0.32 M ammonia
<h3>What is a buffer?</h3>
A buffer is a solution used to stabilize the pH (acidity) of a liquid.
A good buffer system is generally known to contain close or equal concentrations of a weak acid and its conjugate base.
Based on the above explanation, the following represents a good buffer system as they are between their weak acid and conjugate base:
- 0.22 M acetic acid + 0.15 M potassium acetate
- 0.29 M ammonium nitrate + 0.32 M ammonia

Answer:
Her Eid per Ruth Jααte Hαin wo Humse,
αb bαtαo Hum Eid Mαnαye yα unko.
ہر عید پر روٹھ جاتے ہیں وہ ہم سے
اب بتاؤ ہم عید منائے یا ان کو
ik ishq ka gam aafat aur us pe ye dil aafat
ya gam na diya hota ya dil na diya hota
bas ek jhijhak hai haal-e-dil sunaane mein,
ki tera bhi jikr aaega mere is phasaane mein.
kya kahoon kis tarah se jita hoon
gam ko khaata hoon aansoo pita hoon
