Is Calcium oxide an acid, base or alkali?
what is the difference between an alkali and a base?
An alkali is a soluble base. (all alkali are bases but not all bases are alkali)
What soluble mean?
It can dissolve in water
What page in the databook can I find if a substance is soluble in water or not?
What would be the pH of water if we added carbon dioxide
What would be the pH of water if we added Silicon dioxide
neutral (silicon dioxide doesn't dissolve in water)
What would be the pH of water if we added Copper(II) oxide?
neutral, copper (II) oxide is insoluble in water.
What would be the pH of water if we added phosporous oxide
What would be the pH of water if we added potassium oxide
What is a solute?
a solid (eg. SALT)
What is a solvent ?
A liquid (eg: Water)
What is a solution?
When a solute disolve in a solvent (eg: sea water)
What does saturated mean?
Too much solute / when the solute stop dissolving in the solution
What is a precipitate
A soluble substance appears in solution
What is the pH of acids?
Less than 7
What is the pH of water/ neutral solution?
pH of exactly 7
What is the pH of a base/ alkali?
pH more than 7
What is the pH scale a measure of?
The concentration of hydrogen ions (H+) in any given solution
How can the pH be measured?
What is the name of OH-
What is the name for H+
In pure water what is the concentration of H+ and OH- ions?
Hydrogen ions = hydroxide ions
