CALCULATIONS
NaBr, g/L =
where:
Example:
(mL AgNO3 ) (N AgNO3 ) (eq. wt. NaBr) (1000)
(mL sample) (fraction of treated sample) (1000)
mL AgNO3 =mL AgNO3 consumed
N AgNO3 = Normality of AgNO3 in meq./mL
eq. wt. = 102.91 mg/meq NaBr
mL sample = mL sample pipetted into the 100-mL
volumetric
fraction of = mL of filtrate used / total volume of solution
treated sample
1000 = factor to convert meq to eq in the
numerator and mL to L in the denominator
NaBr, g/L = (8.24 mL AgNO3 ) (0.0494 N AgNO3 ) (102.91) (1000)
(5.0) (50/100) (1000)
= 16.6 g/L
