'why we use glycerol in estimation of boric acid in given sample'?
Wiki User
∙ 13y ago
boric acid does not react with NaOH directly. When glycerol is added, the mixture behaves as monobasic and so it can be titrated with alkali using phenolphthalein

How would one determine whether a given sample of aspirin is pure or not?
if the melting point range is between 0.5 to 1 degree celcius
How long are urine samples good for testing?
If properly sealed and stored, urine samples are good for testing up to 24 hours after the sample given. The urine sample should be in a sterile container within a sealed plastic bag and stored in a refrigerator.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
How many moles are in 61.83 g H3BO3?
The formula for H3BO3 is boric acid. The molecular weight of boric acid is 61.83-grams per mole. Thus, the given sample of 61.83-grams equals 1.00-moles of H3BO3.
