- These also contribute significantly to the detergency of the product and sometimes are augmented by the organic sequestrants EDTA or sodium gluconate.
- Total alkalinity is often modified, downwards, by the use of less aggressive alkalis, such as sodium carbonate or sodium metasilicate, and, not infrequently, especially in dishwashing formulations, chlorine release agents such as di and tri chloroisocyanuric acid salts.
- Sodium hypochlorite, potassium permanganate, chlorine and chlorine dioxide are the most common oxidising agents added to water in scrubbing towers.
- Nutrients vital to tree health, such as calcium, magnesium, sodium and potassium, are easily leached out when a high level of acidity occurs.
- Many of these patients will have hypoaldosteronism and in the face of renal sodium loss the diabetic may well be sodium depleted.
- Two agents are commonly used sodium perborate (which is a compound of hydrogen peroxide and sodium metaborate and acts as a solid source of hydrogen peroxide) and sodium hypochlorite (common bleach) although other chlorine release agents are used.
- What is worse is that in glass sodium and calcium are more weakly bonded to oxygen than is silicon.
- Alkalis commonly used range from mild materials such as sodium carbonate (washing soda or soda ash) to sodium metasilicate which is stronger and sodium hydroxide (caustic soda) and potassium hydroxide (caustic potash).
- In the following table they are in order of abundance: Percentage Oxygen 46.6 Silicon 27.7 Aluminium 8.1 Iron 5.0 Calcium 3.6 Sodium 2.8 Potassium 2.6 Magnesium 2.1 Titanium 0.4 Phosphorus 0.2 Manganese 0.1 Hydrogen 0.1
- The Swiss experiment used an original concentration of 50mM of the sodium salt; when equilibrium had been reached 18mM of "fresh" octanoic acid salt had been produced.
- One London architectural practice has already experimented with lighting its own offices with high pressure sodium lamps "bounced" off the ceiling.
- This may result in increased sodium reabsorption with subsequent increased exchangeable body sodium (De Chatel et al, 1977).
