Study Notes
- Some metals react quickly with water, others react slowly, and some not at all.
- Metals react with water to produce metal hydroxide and hydrogen gas.
General Word Equation
- Metal + Water → Metal Hydroxide + Hydrogen
Reactivity of Metals with Water
- Potassium (K) reacts very vigorously with water, producing fizzing, heat, and sparks.
- Sodium (Na) reacts vigorously with water, creating bubbles.
- Calcium (Ca) reacts slowly with water, forming bubbles.
- Magnesium (Mg) reacts very slowly with cold water, but faster with steam.
- Zinc and Iron react only with steam.
- Copper, Gold, and Silver do not react with water, as they are unreactive.
