#1
Front (Question)

When do reactions between metals and acids occur?

Back (Answer)

When the metal is more reactive than the hydrogen in the acid

#2
Front (Question)

Salt def

Back (Answer)

A compound formed when the hydrogen in an acid is wholly, or partially, replaced by metal (or ammonium) ions

#3
Front (Question)

Complete the equation: metal + acid —>

Back (Answer)

metal + acid —> salt + hydrogen

#4
Front (Question)

Why are alkali metals never added to acid?

Back (Answer)

The reaction will be too violent

#5
Front (Question)

How can pure dry crystals be obtained from a solution?

Back (Answer)

• some water is evaporated from the solution by heating it until the point of crystallisation • at this point, the solution is saturated and crystals will appear at the edge of the salt solution being heated in an evaporating dish

#6
Front (Question)

How do you prepare the best sample of salt crystals?

Back (Answer)

salt solution should be left at room temperature for the remaining water to evaporate slowly

#7
Front (Question)

Salts formed when you react metals with HCl (hydrochloric acid)

Back (Answer)

Chlorides (containing Cl- ions)

#8
Front (Question)

Salts formed when you react metals with H2SO4 (sulphuric acid)

Back (Answer)

Sulphates (Containing SO42- ions)

#9
Front (Question)

Salts formed when you react a metals with nitric acid (HNO3)

Back (Answer)

Nitrates (containing NO3- ions)

#10
Front (Question)

What happens when you react magnesium with dilute sulphuric acid

Back (Answer)

• hydrogen ions will be displaced from solution by magnesium (magnesium is more reactive than hydrogen) • magnesium has a stronger tendency to form positive ions than hydrogen has • MgSo4 (magnesium sulphate) + H2 is formed

#11
Front (Question)

Is magnesium oxidised or reduced in a reaction with sulphuric acid

Back (Answer)

• magnesium atoms have lost electrons, so oxidised • Half-equation: Mg(s) —> Mg2+(aq) + 2e-

#12
Front (Question)

When magnesium loses electrons in a reaction with sulphuric acid, where do they go?

Back (Answer)

• magnesium loses two electrons from its outer shell • it gives these electrons to two hydrogen ions in the solution (2H+), forming two hydrogen atoms • these bond to each other (sharing a pair of electrons in a covalent bond) to make a molecule of hydrogen gas (H2)

#13
Front (Question)

Is the reaction between a metal and an acid a redox reaction?

Back (Answer)

• yes • metal atoms always give electrons to the hydrogen ions, displacing hydrogen as a gas and leaving metal ions in the solution
