Determining the acid concentration in everyday substances
What is an acid
types of acids
hydrochloric acid
nitric acid
sulphuric acid
acetic acid
lactic acid
citric acid
properties
characteristics
pH < 7.
Sour taste (though you should never use this characteristic to identify an acid in the lab)
Reacts with a metal to form hydrogen gas.
Increases the H+ concentration in water.
Donates H+ ions.
Turns blue litmus indicator red.
definition
An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.

how to determine concentration
titration
Variables that will affect the outcome
method used
balance (weight error)
temperature
Independent variable (stimulus), the mass of volume of the titrant
equipment used
dependent variable (response), the measured response quantity of pH of the solution (changes depending on the composition of the 2 solutions)
possible errors and limitations
human error
not cleaning equipment properly can result in contamination of solutions which would effect the amount of NaOH titrated
reading the burette wrong
not cleaning equipment properly can result in dilution of solution which would effect the concentration
environment/equipment
temperature of room could effect the composition of the solutions
volumetric pippette could be faulty
tap on burette could be faulty and thus let out more solution then intended
the glassware used to measure out solutions could be faulty and provde the wrong measurements
