SO₂ Calculations from Titre

M = Molarity (M)

V = Volume (ml)

T = titre (ml) of 0.01 M NaOH

titration record sheet multiple

M

V

SO₂ = T * 16

				*T M * 16**
SO₂		=		-------------------		=		80TM/V
				*V 20 * 0.01**

i.e.

				M (NaOH)			X		ml (titre)		X		16
SO₂ ppm		=		-----------------	---------		---------	---------	---------	---------	---------	---------	-----------------
				ml (sample vol.)			X		20 ml		X		0.01 M (NaOH)
