Concentration Calculations
Titrations are experiments that let you find the volumes needed for two solutions to react together completely
If you know the concentration of one of the solutions, you can use the volumes from the titration experiment, along with the reaction equation, to find the concentration of the other solution
You might remember the formula for working out the concentration of a substance in mol/dm3, this time it’s used in a triangle
No of moles
Concentration x volume
Work out how many moles of the known substance you have using equation
Work out concentration of unknown stuff
To find the concentration in g/dm3 start by finding the concentration in mol/dm3 using the steps above
Then convert the concentration in mol/dm3 to g/dm3 using the equation mass=moles x M
Work out the relative formula mass for the acid
Convert the concentration in moles into concentration in grams
