What does a litmus test tell us?
What is a precipitation reaction?
What does it mean if a substance is soluble?
True or False: Most hydroxides are insoluble.
Define Hydrocarbon
Give the cation and flame colour of - Lithium
Give the cation and the flame colour of - Sodium
Give the cation and the flame colour of - Potassium
Give the cation and the flame colour of - Calcium
Give the cation and the flame colour of - Copper
List the steps of testing for positive ions
State why flame photometry works better
Which ion is this - Fe2+

What do you have to do if you have two white precipitates formed?
How do you know if the metal ion is Aluminium or Calcium?
State the chemical equation for copper nitrate mixed with sodium hydroxide
what is the net ionic equation for
Cu (NO3)2 (aq) + NaOH (aq) --> Cu (OH)2 (s) + NaNO3 (aq)
How do you find a net ionic equation?

Define nanoparticle
cube-shaped nanoparticle has sides of 20nm. calculate its total surface area, its volume, and surface area to volume ratio
If the total surafce area to volume ratio is higher what does that mean?
