The most important is to figure out the structure of C7H6O6S. Although there are many possibilities, Google search points out to the most popular structure: 5-Sulfosalicylic acid http://www.jianxin-chem.cn/images/jiegoushi-1.jpg Second, it's important to know the sequence of addition, conditions (te...

No. At least not directly. Even if both electrodes were completely covered with rust, when completely exposed to water, the conductivity only depends on the surface of iron. The surface may somewhat increase due to rusting that in turn will make the surface of iron electrodes rougher. Still, the mai...

Because saturated solution of Ca(OH)2 may contain undissolved Ca(OH)2 solid (by definition of saturated solution). Additionally Ca(OH)2 is almost always contaminated with CaCO3 that formed by absorption of CO2 from air. All these solids are expected to retain on a filter paper, and the paper will be...
