Acids, Bases and Salts
- pH 7
- Acids = less than 7
- Bases = more than 7
- ALKALIS
- ALKALIS
- NEUTRAL CHEMICALS have pH7
- NOT ACIDS
- NOT BASES
- Dont change the colour of Litmus Paper
- Turn Universal Indicator GREEN
- WATER
- Parafin
- NOT ACIDS
- Acids = less than 7
- Acids
- Turn blue litmus paper RED
- Strong acids turn
universal indicator red
- Weak Acids turn
universal indicator
hyellow or orange
- Turn blue litmus paper RED
- Bases
- Usually metal oxides or metal hydroxides
- Copper oxide
- Sodium Hyrdroxide
- Copper oxide
- Not all bases dissolve in water
- Most do
- Copper Oxide doesnt
- Soduim Hydroxide can
- Most do
- If a base can dissolve in water, it is an Alkali
- the stronger the alkali the higher the pH value
- Turn Red Litmus paper BLUE
- turn universal
indicator blue or
purple if they are
strong
- turn universal
indicator blue green isa
they are weak
- the stronger the alkali the higher the pH value
- Usually metal oxides or metal hydroxides
- Salts
- Compounds
- Sodium Chloride
- edible salts
- edible salts
- Formed by
acids reacting
with bases,
carbonates or
metal
- Acids and Bases
- Reaction between an acid and a base
is called NEUTRALISATION
- It produces a salt and water
- Reaction between an acid and a base
is called NEUTRALISATION
- Acids and carbonate
- Forms salts, water and carbon dioxide
- CO2 causes bubbling during the reaction
- Limewater turns a cloudy
white when carbon dioxide
is bubbled through it
- Forms salts, water and carbon dioxide
- Acids and Reactive metals
- Salt and hydrogen gas is formed
- No water
- No water
- Hydrogen can be
detected with a lighted
splint and makes a
squeaky pop
- Salt and hydrogen gas is formed
- Salt names
- Two parts, one
from the base and
one from the acid
- Sodium Hydroxide + Hydrochloric Acid = Sodium Chloride
- Sodium comes from the Base
- Chloride comes from the acid
- Sodium comes from the Base
- Sulphuric acids make sulphates
- Nitrate acids = Nitrate
- Two parts, one
from the base and
one from the acid
- Making a salt from an alkaline solution
- Formed when a base dissolves in water
- Add acid to the alkali very slowly
- use universal
indiciator to tell when
you reach a neutral
state
- IT WILL GO GREEN
- IT WILL GO GREEN
- use universal
indiciator to tell when
you reach a neutral
state
- Makes salt and water
- Formed when a base dissolves in water
- Compounds
- Carbonate
- Chalk
- Marble
- Limestone
- Chalk
