acid-base-ph-oxide-salt
acid
acid is an negative acid base ion + positive H ion
examples
HCl -> H(+) + Cl(-)
H2SO4 -> 2H(+) + SO4(2-)
properties of acid
changes colour of obj
example: acids change litmus to red
reacts with metal
example: Zn + 2HCl -> ZnCl2 + H2^
some uses
HCl
clensing metal
creating rubber, elastic material
making medicine
H2SO4
making paint
making car batteries
making elastic material
CH3COOH
making elastic material
making medicine
making pesticides
bases
bases are metal ions bonded with OH(-) ions
example: NaOH -> Na(+) + OH(-)
properties
changes colours of obj
example: bases change litmus colour to blue
reacts with acid
reacts with acid to make water + salt
example: NaOH + HCl -> NaCL + H2O
ph
the ph scale goes from 1 to 12
acid is 1-6
neutral is 7
base is 8-12
ph is how acidic/basic substances are
ph of our environments have effects on our lives
example
fishes can only live in 7,5 - 8 ph
our blood can live in 7,35-7,45 ph
ways to know ph
universal indicator paper
acid: red - yellow
neutral: green
base: blue - purple
oxide
metals/nonmetals bonded with O ion
oxide types
base oxide
oxides that react with acid to make salt and water
acid oxide
oxides that react with base to make salt and water
amphoteric oxide
reacts with both acids and bases to make salt and water
neutral oxide
cannot react with acids and bases
