The pH range is from 0 to 14. Classify these oxides as acidic or basic. Also is there an equation to represent this? Sodium acetate is a basic salt; the acetate ion is capable of deprotonating water, thereby raising the solution’s pH. An amphoteric oxide is one which shows both acidic and basic properties. Why does resistance increase when current decrease? This would be something like distilled water. The key difference between acidity and basicity is that acidity causes a low pH whereas basicity causes a high pH i… 3. We examine them under four titles; acidic and basic oxides, neutral oxides, amphoteric oxides and peroxides; 1) Acidic Oxides: They are oxides which combine with bases and form salt.
