Acids and Bases Worksheets - 15 Worksheets Library - Free Printable

Explanation:
We are given 10 acid-base reactions. For each, we need to:
1. Check if the equation is balanced (same number of each atom on both sides).
2. Label the products — in acid-base reactions, the products are usually a salt and water. The salt is made from the cation of the base and the anion of the acid.

Let’s go one by one:

---

1. HCl + NaOH → NaCl + H₂O
- Left: H=1+1=2, Cl=1, Na=1, O=1
- Right: Na=1, Cl=1, H=2, O=1
✔ Balanced.
Products: NaCl (salt), H₂O (water)

---

2. H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
- Left: H=2+2×1=4, S=1, O=4+2×1=6, Na=2
- Right: Na=2, S=1, O=4+2×1=6, H=2×2=4
✔ Balanced.
Products: Na₂SO₄ (salt), H₂O (water)

---

3. 2HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + 2H₂O
- Left: H=2×1 + 2 = 4, N=2, O=2×3 + 2 = 8, Ca=1
- Right: Ca=1, N=2, O=6 + 2 = 8, H=4
✔ Balanced.
Products: Ca(NO₃)₂ (salt), H₂O (water)

---

4. H₃PO₄ + Al(OH)₃ → AlPO₄ + 3H₂O
- Left: H=3+3=6, P=1, O=4+3=7, Al=1
- Right: Al=1, P=1, O=4+3=7, H=3×2=6
✔ Balanced.
Products: AlPO₄ (salt), H₂O (water)

---

5. 2HBr + Ba(OH)₂ → BaBr₂ + 2H₂O
- Left: H=2×1 + 2 = 4, Br=2, Ba=1, O=2
- Right: Ba=1, Br=2, H=4, O=2
✔ Balanced.
Products: BaBr₂ (salt), H₂O (water)

---

6. HF + RbOH → RbF + H₂O
- Left: H=1+1=2, F=1, Rb=1, O=1
- Right: Rb=1, F=1, H=2, O=1
✔ Balanced.
Products: RbF (salt), H₂O (water)

---

7. H₂CO₃ + Sr(OH)₂ → SrCO₃ + 2H₂O
- Left: H=2+2=4, C=1, O=3+2=5, Sr=1
- Right: Sr=1, C=1, O=3+2=5, H=4
✔ Balanced.
Products: SrCO₃ (salt), H₂O (water)

---

8. 2HClO₄ + Mg(OH)₂ → Mg(ClO₄)₂ + 2H₂O
- Left: H=2×1 + 2 = 4, Cl=2, O=2×4 + 2 = 10, Mg=1
- Right: Mg=1, Cl=2, O=2×4 + 2 = 10, H=4
✔ Balanced.
Products: Mg(ClO₄)₂ (salt), H₂O (water)

---

9. HClO + LiOH → LiClO + H₂O
- Left: H=1+1=2, Cl=1, O=1+1=2, Li=1
- Right: Li=1, Cl=1, O=1+1=2, H=2
✔ Balanced.
Products: LiClO (salt), H₂O (water)

---

10. H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Wait — this is identical to #2! Let’s double-check:
- Left: H=2 + 2×1 = 4, S=1, O=4 + 2 = 6, Na=2
- Right: Na=2, S=1, O=4 + 2 = 6, H=4
✔ Balanced.
Products: Na₂SO₄ (salt), H₂O (water)

All equations are already balanced as written. So no changes needed.

Now, labeling products: In every case, the products are:
- A salt (ionic compound formed from the metal cation and acid anion)
- Water (H₂O)

So for each reaction, just list the two products.

Final Answer will list each reaction with its products labeled.

Final Answer:
1. NaCl (salt), H₂O (water)
2. Na₂SO₄ (salt), H₂O (water)
3. Ca(NO₃)₂ (salt), H₂O (water)
4. AlPO₄ (salt), H₂O (water)
5. BaBr₂ (salt), H₂O (water)
6. RbF (salt), H₂O (water)
7. SrCO₃ (salt), H₂O (water)
8. Mg(ClO₄)₂ (salt), H₂O (water)
9. LiClO (salt), H₂O (water)
10. Na₂SO₄ (salt), H₂O (water)
