First Titration

Neutralisation Equation

Acid + Base → Salt + Water

So lets set out to prove this

OC37 / 38

titrate HCl against NaOH, and get some thing

Titration is the use of a burette, to determine the volume of a solution needed to completely react with a particular volume of another solution.

1. Set up a burette with hydrochloric acid (HCl).2. Using a pipette place a particular volume e.g. 20 cm3 , of sodium hydroxide (NaOH) solution in a conical flask.

3. Add a few drops of methyl Orange to the sodium hydroxide solution.

4. The sodium hydroxide solution is now orange.

5. Slowly run the acid into NaOH solution while swirling the flask.

6. When the indicator turns the colour of pH 7 (PINK) STOP ADDING the ACID.

7. Note the volume of acid added to neutralise the base.

Are these used volumes the same? ?

NO, repeat until they are the same

IF They are the same .....

8. Repeat with exactly the same volumes without the indicator.

and prepare a sample of NaCl.

9. A pure sodium chloride solution is in the beaker. Pour this into an evaporating dish!

10. Pure sodium chloride salt remains when the water is evaporated.

Salts A salt is an ionic compound composed of a metal ionically bonded to a non-metal.

A salt is formed by the replacement of the hydrogen of an acid by a metal.

Different salts are produced from different acids and different metals.

A titration is a method of measuring the relative strengths of Acids vs Bases. In our titration we found that the _______ was stronger.

A set amount of acid will neutralise a set amount of base, In our experiment _____cm3 will neutralise ____ cm3 of base.

A Neutralisation reaction occurs when an Acid completely reacts with an Acid to form Water and Salt.
