The lead ions are … The bromide ions are negatively charged and are called anions. Answer (1 of 2): Magnesium sulfate (MgSO4) and water (H20) react to form magnesium heptahydrate (MgSO4*7H2O).which is a solid substance made of translucent white crystals. (b) Molten lead bromide conducts electricity … Thus, electrons flow like a “sea of electrons” through metals. what is the nature of forces that holds the particles in this solid? However, if I have two poles of metal placed in a beaker and put a voltage between them, the current flowing in the metal is made of electrons, while the current flowing in the water is made … The half equations are. Another common solid that conducts electricity is graphite - yes, the same graphite as in your pencil. Table salt (main ingredient NaCl, sodium chloride), like Epsom salt, alum, fixer, washing soda, and baking soda, produces ions when dissolved in water. a) FeF2. 6 years ago.
