Problem 18.74

Calcium oxalate (CaC2O4) is insoluble in water. This property has been used to determine the amount of Ca21 ions in blood. The calcium oxalate isolated from blood is dissolved in acid and titrated against a standardized KMnO4 solution as described in 18.72. In one test, it is found that the calcium oxalate isolated from a 10.0-mL sample of blood requires 24.2 mL of 9.56 3 1024 M KMnO4 for titration. Calculate the number of milligrams of calcium per milliliter of blood.

Step 1 of 3

Friday, September 2, 2016 NHM 361-921: Module 2 Notes (CH. 15) “Body Fluids” • water is the most abundant molecule in the human body - accounting for 2/3 of total body weight • body water can be categorized as intracellular or extracellular fluid INTRACELLULAR FLUID- body fluid located within the cells EXTRACELLULAR FLUID- body fluid located outside the cells • can be divided further into interstitial fluid and plasma INTERSTITIAL FLUID- fluid surrounding individual cells and fluid in the lymph vessels PLASMA- the liquid portion of whole blood 1 Friday, September 2, 2016 Unique Properties of Water: • water cushions and lubricates the body’s tissues and organs • water is a great solvent due to its polarity • water is an excellent transport medium of nutrients to cells and tissues HYDROPHILIC- water loving molecules that have a sufficient number of polarized bonds or ionized groups in order for it to dissolve in water HYDROPHOBIC- molecules that are electrically neutral and are not attracted to the (+) and (-) charges of H2O AMPHIPATHIC MOLECULES- are those that consist of both hydrophilic and hydrophobic parts (think fatty acids) • in aqueous environments. these molecule types will typically cluster together so their polar ends will face the water & the non polar ends will be oriented away from the water HYDROLYSIS- breaking of chemical bond
