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.
Synthesis is the act of combining elements to form something new. If you describe your bedroom decor as a synthesis of Andy Warhol and Punk Rock, we'll know you mean a mixture of these two styles. Synthesis is just as comfortable in the concrete realm as it is in the abstract. Scientists use it to talk about what happens when chemicals combine â think of photosynthesis: the process by which plants synthesize light, carbon dioxide, and water to produce food. If you call a movie Batman meets Titanic, then that's synthesis as well.
