#12. A soluble base is called?
#13. Solutions of more than pH 7 are?
#14. Complete the following equation: MgO (s) + H₂SO₄ (aq) → .... + ....
Select all that apply:
Neutralisation reactions follow the general structure –
metal oxide acid = salt water
the acid produces hydrogen ions and the metal oxide produces oxide ions – these combine to make the water
the salt is comprised of the remaining products – the metal and the other element from the acid
in this case, the other element is chlorine
The naming convention is to put the metal first for the salt created

#15. During a neutralisation reaction which salt is formed from nitric acid?
#16. Complete the equation: H⁺(aq) + OH⁻(aq) → ....
Remember:
acids produce an excess of hydrogen ions
alkalis produce an excess of hydroxide ions
hydrogen ions and hydroxide ions come together to make water which is neutral.
