Investigation of Energy changes in reaction between NaOH and HCL.
Aim
My aim is to find out the heat given out during the neutralisation of HCL and NaOH. HCL will be a constant and NaOH will be varied and mixed with H2O.
Background Knowledge
Neutralisation is when an acid reacts with an alkali to form a salt and water.
Eg.
HYDROCHLORIC ACID + SODIUM HYDROXIDE SODIUM CHLORIDE+WATER
HCL (aq) + NaOH (aq) NaCl (aq) + H2O (l)
ACID + ALKALI SALT + WATER
In the above equation the acid HCL is being reacted with the alkali NaOH and a salt NaCl and water is produced.
Properties Of Acids & Alkalis
Acids
Alkalis
Acids corrode active metals.
Alkalis corrode protein.
Acids turn blue litmus into red.
Alkalis turn red litmus paper into blue.
Acids taste sour.
