Balanced Chemical Equation
An equation that shows the number of atoms for each element in reactants and products are equal.
Metal Oxides
Oxides formed by metals that are partially soluble in water and typically have alkaline properties.
Non-Metal Oxides
Oxides formed by non-metals that are gaseous in state and give acidic solutions when dissolved in water.
Amphoteric Oxides
Oxides that can neutralize both acids and bases, examples include aluminum oxide and zinc oxide.
pH Indicator
A substance that changes color in response to changes in pH, allowing the determination of acidity or alkalinity.
Calcium Oxide
A metal oxide used in experiments to observe its reaction with water and determine its solubility.
Properties of Metal Oxides
Typically solid, partially soluble, and alkaline in nature.
Properties of Non-Metal Oxides
Typically gaseous, soluble in water, and form acidic solutions.
Solubility
The ability of a substance to dissolve in a solvent, which can be tested using universal indicators.
