first as an anticoagulant and second to be sure the hematocrite is lower than 35%.
Now days the labs use EDTA as anticoagulant (sample stability is much better 24 hours in stead of 4 hours) but still need to dilute the blood sample regarding the hemathocrite value. This regarding ICSH recommendations for measurement of erythrocyte sedimentation rate.
They are two completely different substances Sodium nitrate is NaNO3, a compound of sodium, nitrogen, and oxygen. It is an inorganic salt and a strong oxidizer. It is sometimes used as a fertilizer or in black powder. There are 3 variants of sodium citrate: Monosodium citrate (NaH2C6H5O7), disodium citrate (Na2HC6H5O7), and trisodium citrate (Na3C6H5O7). All three are compounds of sodium, hydrogen, carbon, and oxygen. They are organic salts commonly used as food additives.
sodium citrate bond
yes you can use either trisodium citrate or sodium citrate
Sodium citrate can be used as a pH buffer as well as a chelating agent to tie up free radicals in a product and also as an antioxidant.
sodium citrate (Na3C6H5O7) molar mass=258.069g/mol

sodium citrate bond
Black top (sodium citrate tube) or light blue tube. They both contain sodium citrate. I failed this question on my final, I knew a black top tube is used but it was not given to me as a choice. I did not think hard enough to come to the conclusion that a light blue tube would be another option.
laxative
yes you can use either trisodium citrate or sodium citrate
sodium citrate is some times used as an acidity regulator in drinks and also emulsifier for oils when making cheese
Disodium citrate is used in drinks or in foods as an antioxidant or as an acidity regulator.
No it's not caustic. In fact the pH is about 7
Yes, the source of sodium citrate is natural. Sodium citrate occurs naturally in citrus fruits such as pineapples, lemons and oranges.
two water molecules
Citric acid and sodium hydroxide combined makes sodium citrate.
