Process of finding exact concentration by titration against a known standard
Absorbs water vapour from air and dissolves in it
It's deliquescent, absorbs water so can't weigh exactly
HCl+NaOH→NaCl+H2O\text{HCl} + \text{NaOH} \to \text{NaCl} + \text{H}_2\text{O}HCl+NaOH→NaCl+H2O
1:1 ratio
Standard HCl solution
To help observe colour changes
Methyl orange
Yellow to red (or pink)
Solution becomes acidic
25 cm325 \text{ cm}^325 cm3
Within 0.1 cm30.1 \text{ cm}^30.1 cm3
First deionised water, then with NaOH solution
Highly caustic, causes severe burns to skin/eyes
Moles of HCl = Moles of NaOH (1:1 ratio)
