PPT-REDOX: IRON, SULFUR, & SILICA

Redox Potential pE log free electrons When corrected to pH 7 H OH called E h When E h positive oxidizing environment When E h negative reducing environment . What is silica Silica is a natural substance found in most rocks sand and clay and in products such as bricks and concrete Silica is also used as filler in some plastics In the workplace these materials create dust when they are cut sanded carved et Databases treating redox reactions must include either .
