Flashcards in Chemistry Ka3 Deck (40):
What does the name of a salt depend on?
The metal used
The acid used
The positive ion in the base, alkali or carbonate used
When magnesium reacts with hydrochloric acid, two products are hydrogen and magnesium. What is the equation?
Mg + 2HCl --> MgCl₂ + H₂
What is this called?
A redox reaction because it has both reduction and oxidation
Fe - 2e⁻ --> ???
What is a base?
An insoluble metal hydroxide (magnesium hydroxide) and a metal oxide (copper oxide)
What is insoluble?
Something that doesn't dissolve in water
What is an alkali?
A soluble metal hydroxide (sodium hydroxide)
What is an example of a metal carbonate?
What is potassium hydroxide?
What is zinc hydroxide (insoluble)
What is magnesium oxide?
What is calcium oxide?
How do u remember making salts?
What does MASH stand for?
Metal + acid --> salt + Hydrogen
What does BASH stand for?
Base + acid --> salt + Water
What does AASH stand for?
Alkali + acid --> salt + water
What does MCASHC stand for?
Metal carbonate + acid --> salt + water + carbon dioxide
Hydrochloric acid +magnesium oxide = ???
Sulfuric acid + copper hydroxide =
Nitric acid + potassium oxide =
A student wanted to make potassium nitrate. Why would it not be sensible for her to do this?
Because potassium is very reactive and may explode when in contact with nitric acid
A student wanted to make copper sulphate. Why would it not be sensible for her to react copper with sulfuric acid?
It will not react as the copper will not displace the hydrogen because it is less reactive
If a gas was produced what might you see?
What happens when a metal reacts?
It gets smaller
What is the symbol for magnesium sulfate?
What is the symbol for hydrogen?
What is the ionic equation for neutralisation?
H⁺ (aq) + OH⁻ (aq) --> H₂O (L)
What is this state symbol: (s)
What is this state symbol (g)
What is this state symbol: (L)
What is this state symbol: (aq)
Magnesium bromide Mg²⁺ Br⁻
Aluminium chloride Al³⁺
Aluminium hydroxide Al³⁺ OH⁻
Al³ ⁺ OH⁻ Al(OH),3
What is soluble
Dissolves in water
What is insoluble
Doesn't dissolve in water
What do all acids release into a solution when added to water?
H⁺ (aq) ions
What is the reaction between an acid and an alkali called?
Acid + carbonate -->
salt + water + carbon dioxide
