What Are the Pros and Cons of a Sulfuric Acid Drain Cleaner Toxic Substances Portal Sulfur Trioxide Sulfuric Acid
Aug 06 32 There also are a number of disadvantages to using a sulfuric acid drain cleaner The largest one is that sulfuric acid is a highly toxic caustic material that will emit harmful fumes the second it is exposed to air These fumes can cause severe eye irritation and have the potential to burn the tissue inside the nose and lungs if inhaled deeplyJan 21 32 Exposure to sulfuric acid from accidental contact with or misuse of sulfuric acid containing consumer products is the most likely way your child could be exposed products that contain sulfuric acid include drain and toilet bowl cleaners and some acid car batteri

Leaching of Metals from Hydrometallurgical Residue by What Chemicals Cause PVC Sink Drain Pipes to Melt or
leaching time the particle size and the sulfuric acid concentration was examined Results of leaching studies that the recovery extraction of Zn Fe and Cu for hydrometallurgical residue increases with increasing acid concentration and temperature while it decreases with particle sizeThree types of drain cleaners can cause PVC pipes to become soft acids caustics and oxidizers The active ingredients of acid cleaners are usually sulfuric acid or hydrochloric ac Oxidizers often contain sodium hypochlorite while the active ingredient in caustic drain cleaners is usually sodium hydroxide which is also known as lye

Kinetics of sulfuric acid leaching of cadmium from Cd Ni Sulfuric Acid Chlorine Bleach Reaction Sciencing
A maximum cadmium recovery of 95 was obtained by leaching with 17 M sulfuric acid for 15 min at 25 176 C with 1/8 solid/liquid ratio agitated at 400 rpm The results showed that it is possible to separate copper and lead from Cd Ni zinc plant residues through selective leachingMar 13 32 Chlorine bleach is a solution of sodium hypochlorite and water Chlorine gas is produced when sulfuric acid is mixed with chlorine bleach This reaction is a function of the change in pH of the solution from alkaline to acidic combined with the strong oxidant properties of hypochlorous ac Acids and Bases An acid is
