The Reactivity Series Flashcards
Chemical Changes (18 cards)
What does the reactivity series list?
Metals in order of their reactivity towards other substances
How is a metal’s reactivity determined?
By how easily they lose electrons - forming positive ions
What happens to metals when they react with water or acid?
They lose electrons and form positive ions
What is the general trend in the reactivity series?
The higher a metal is in the reactivity series, the more easily it reacts with water or acid
What is the equation for the reaction of an acid with a metal?
Acid + Metal -> Salt + Hydrogen
What indicates the speed of the reaction between a metal and an acid?
The rate at which bubbles of hydrogen are produced
How do very reactive metals react with acids?
They react explosively
Which metals do not react with cold, dilute acids?
Copper
What happens when magnesium reacts with dilute acids?
It reacts vigorously
What is the reaction of zinc with hydrochloric acid?
Zn + 2HCl -> ZnCl2 + H2
How can you investigate the reactivity of metals?
By measuring the temperature change of the reaction with an acid or water
What is the reaction equation for a metal reacting with water?
Metal + Water -> Metal Hydroxide + Hydrogen
Which group of metals will react with water?
Potassium, sodium, lithium, and calcium
What do less reactive metals like zinc, iron, and copper do in relation to water?
They won’t react with water
