Actually,
there is no explicit task or question stated in the image you uploaded — it only shows a grid of 12 chemical ions labeled (a) through (l).
Since no specific question was provided (e.g., “Which are acids?”, “Which are bases?”, “Which can act as ligands?”, “Which are polyatomic?”, etc.), I cannot solve a problem that isn’t defined.

✔ However, I can help you by providing
common categories these ions fall into, which might be what the original task intended. Here’s a breakdown:
---
🔬 Acids / Conjugate Acids:
These can donate protons (H⁺):
-
(a) NH₄⁺ — ammonium ion (conjugate acid of NH₃)
-
(b) H₃O⁺ — hydronium ion (strong acid in water)
---
🧪 Bases / Conjugate Bases:
These can accept protons:
-
(c) CN⁻ — cyanide ion (conjugate base of HCN)
-
(d) SCN⁻ — thiocyanate ion (weak base)
-
(e) CO₃²⁻ — carbonate ion (conjugate base of HCO₃⁻)
-
(f) ClO₃⁻ — chlorate ion (very weak base)
-
(g) SO₄²⁻ — sulfate ion (conjugate base of HSO₄⁻)
-
(h) PO₄³⁻ — phosphate ion (conjugate base of HPO₄²⁻)
-
(i) SO₃²⁻ — sulfite ion (conjugate base of HSO₃⁻)
-
(j) NO₂⁻ — nitrite ion (conjugate base of HNO₂)
-
(k) BF₄⁻ — tetrafluoroborate ion (very weak base, often used as non-coordinating anion)
-
(l) NO₃⁻ — nitrate ion (conjugate base of HNO₃; very weak base)
---
⚖️ Amphoteric?
None of these are typically amphoteric — they’re mostly either acidic or basic conjugates.
---
💎 Ligands (in coordination chemistry):
Ions that can bind to metal centers via lone pairs:
-
(c) CN⁻ — strong field ligand
-
(d) SCN⁻ — can bind via S or N (ambidentate)
-
(e) CO₃²⁻ — can act as bidentate ligand
-
(g) SO₄²⁻ — can coordinate weakly
-
(h) PO₄³⁻ — can coordinate
-
(i) SO₃²⁻ — can coordinate
-
(j) NO₂⁻ — ambidentate ligand (binds via N or O)
-
(k) BF₄⁻ — usually non-coordinating
-
(l) NO₃⁻ — can coordinate weakly

❗ Important Note:
If this was part of a multiple-choice or matching exercise (e.g., “match the ion with its conjugate acid/base” or “identify the spectator ions”), you’d need to provide the actual question.
---
📌
Please clarify the task! For example:
- Are you supposed to identify acids vs. bases?
- Sort them by charge?
- Find which ones are common ligands?
- Classify them as oxidizing/reducing agents?
Once you specify the question, I’ll give you a precise, step-by-step solution.

✔ In summary: The image displays 12 ions. Without a stated task, I’ve categorized them by common chemical roles. Let me know what the actual problem is, and I’ll solve it for you!
