In acid-base balance, the kidney is responsible for 2 major activities: 1  Reabsorption of filtered bicarbonate: 4,000 to 5,000 mmol/day. 2  Excretion of the fixed acids (acid anion and associated H +): about 1 mmol/kg/day..4.3 Bicarbonate Reabsorption. Daily filtered bicarbonate equals the product of the daily glomerular filtration rate (180 l/day) and the plasma bicarbonate concentration (24 mmol/l). This is 180 x 24 = 4320 mmols/day (or usually quoted as between 4000 to 5000 mmols/day).
Mixing water and sugar produces a mixture that is called a solution. In chemistry labs, this is often an experiment used to demonstrate the solubility of a solute in a solvent. In this experiment, the solute is sugar, and water is the solvent. Continue Reading. To form the solution, sugar dissolves in a glass of water.
MIXTURES : When two or more substances are mixed together but not chemically joined they are called as mixtures. Mixtures are absolutely everywhere you look. Mixtures form for most things in nature. Rocks, air, or the ocean, they are just about anything you find. They are substances held together by physical forces, not chemical. This statement means that the individual molecules enjoy being near each other, but their fundamental chemical structure does not change when they enter the mixture. The methods of separation of mixtures depend on the constituents of the mixtures.
