**Question 8**

Which equation shows the net ionic equation for the neutralization of a strong acid with a strong base?

- O HBr (aq) + OH⁻ (aq) → H₂O (l) + Br⁻ (aq)
- O H⁺ (aq) + F⁻ (aq) + Na⁺ (aq) + OH⁻ (aq) → H₂O (l) + NaF (aq)
- O HBr (aq) + Na⁺ (aq) + OH⁻ (aq) → H₂O (l) + Na⁺ (aq) + Br⁻ (aq)
- O H⁺ (aq) + OH⁻ (aq) → H₂O (l)
- O HF (aq) + OH⁻ (aq) → H₂O (l) + F⁻ (aq)

**Question 9**

Which combination could form a buffer?

- O HCl and NaCl
- O HF and HCN
- O H₃PO₄ and K₃PO₄
- O HCN and KCN
