Practice Chemical Property in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A characteristic that describes a substance's ability to undergo a chemical change and form new substances with different compositions and properties.
Properties you can only discover by trying to react the substance — they describe what it can become, not what it looks like.

Example 1
hardTrue or false: corrosion resistance is a chemical property.
Example 2
mediumHydrogen peroxide bleaches hair. Is the bleaching action a chemical or physical property of ?
Example 3
mediumFrom this list, select the chemical properties: shiny, reacts with oxygen, density 8.9 g/cm³, flammable, ductile.
Example 4
challengeExplain why 'iron rusts' is a chemical property of iron, but 'iron is attracted to a magnet' is a physical property, even though both describe how iron behaves.
Example 5
challengeYou are given two white powders that look identical (same color, similar density). Describe one chemical-property test that distinguishes them and explain why a physical test would fail here.
Example 6
easyDensity is a ____ property.
Example 7
mediumWhy is 'reacts with oxygen' a chemical property but 'dissolves in water' a physical property?
Example 8
challengeDesign an experiment to determine whether an unknown white powder is calcium carbonate (which fizzes in acid) or table salt (which does not). State which chemical property your test uses.
Example 9
easyIs 'reactivity with water' a chemical property?
Example 10
mediumA label warns: 'reacts violently with water, corrodes metals, and is a yellow solid melting at 115 °C.' Identify the chemical properties.
Example 11
hardYou have two clear liquids that look identical. Describe a chemical-property test that could tell them apart.
Example 12
easyIs 'reacts with water to form a base' a chemical property of sodium?
Example 13
hardWhy is 'enthalpy of combustion = -890 kJ/mol' considered a numerical chemical property of methane?
Example 14
easyName two chemical properties of a typical metal like sodium.
Example 15
mediumIs 'pH = 1 (strongly acidic)' a chemical property?
Example 16
hardGold does not tarnish in air and does not react with most acids. Silver tarnishes when exposed to sulfur compounds in air. Compare the chemical properties of gold and silver, and explain why gold is preferred for long-lasting jewelry.
Example 17
easyIs 'ability to neutralize acids' a chemical property of a base?
Example 18
hardA safety sheet says: 'reacts with water, density 0.97 g/cm³, melts at 98 °C, ignites in air on cutting.' List two chemical properties.
Example 19
easyColor is a ____ property.
Example 20
mediumMagnesium is a silver-gray ribbon that ignites in air to a brilliant white flame, producing white MgO. List the chemical properties demonstrated.
