Acids and bases have unique tastes and properties, with indicators like litmus and red cabbage assisting in identifying them, along with specific compounds like HCL or NaOH. Reactions with metals, metal carbonates, and oxides, along with conductivity, pH measurement, and dilution with water, all play key roles in understanding acids and bases.
Insights
- Acid-base indicators such as litmus and red cabbage are essential tools for identifying acids and bases, while olfactory indicators like onions can also detect these compounds based on smell changes.
- The pH scale is crucial for measuring acidity or basicity, with neutral substances at pH 7 and stronger acids or bases closer to 0 or 14, showcasing the spectrum of chemical properties in acids and bases.

Chemical compounds, indicators, reactions, and pH scale.
- Acids and bases are chemical compounds with distinct tastes and properties.
- Acid-base indicators like litmus, red cabbage, and synthetic indicators help identify acids and bases.
- Specific compounds like HCL, H2SO4, and NaOH can be tested with indicators to determine their acidic or basic nature.
- Olfactory indicators like onions can also detect acids and bases based on smell changes.
- Reactions of acids with metals and metal carbonates produce salts and hydrogen gas.
- Metal oxides reacting with acids form salts and water, while non-metallic oxides with bases produce salts.
- Acids and bases conduct electricity due to the ions they produce in water.
- Dilution of acids or bases with water decreases ion concentration and releases heat.
- The pH scale measures acidity or basicity, with neutral substances at pH 7 and stronger acids or bases closer to 0 or 14.
