âThere are a number of physical signs of kidney disease, but sometimes people attribute them to other conditions. Also, those with kidney disease tend not to experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine.
SULFUR DIOXIDE is acidic. Reacts exothermically with bases such as amines, amides, metal oxides, and hydroxides. Frequently used as a reducing agent although it is not a powerful one. Acts as a reducing bleach to decolorize many materials.
Sulfur dioxide has an irritating odor and is a poisonous gas. Care must be taken when handling SO2(g). Exposure to concentrations as low as 8 ppm will produce coughing. If you start coughing due to SO2 inhalation, leave the laboratory to seek fresh air. Deadly concentrations for rats start at 1000 ppm.
