metal compounds that can neutralise an acid
hydroxides, oxides and carbonates.
acids contain
H+ (aq)
acids are
corrosive and can breakdown lots of materials.
what is formed when an acid is neutralised
a salt.
a titration is used to find
the unknown concentration of an acid or an alkali
electrolysis of an acid always produces
hydrogen gas at the negative electrode
neutralisation is a reaction that
decreases the hydrogen ion concentration
what is used to determine whether something is an acid, alkali or neutral
universal indicator
some common acids are made by dissolving
non-metal oxides in water
when ____ of ____, _____ and _____ dissolve in water in the atmosphere they form ________.
when OXIDES of CARBON, SULFUR and NITROGEN dissolve in water in the atmosphere they form ACID RAIN.
soluble non-metal oxides form
acids
soluble metal oxides form
alkalis
common: hydrochloric acid
HCl
common: sulphuric acid
H₂SO₄
common: nitric acid
HNO₃
common: sodium hydroxide
NaOH
common: ammonium hydroxide
NH₄OH
common: calcium hydroxide
Ca(OH)₂
insoluble oxides are
neutral
all acidic solutions are
ionic
all acids contain
hydrogen
ph is dependent on the
concentration of hydrogen ions in a solution
when water dissociates it forms an
equal amount of hydrogen ions and hydroxide ions so the pH is 7
acids are solutions containing what concentration of hydrogen and hydroxide ions?
more hydrogen ions than hydroxide ions
