The compound is hygroscopic (absorbs water) and dissolves well with the formation of acids. In a solution they are in the balance: 2H₂CrO₄ = H₂Cr₂O₇ + H₂O: CrO₃ + H₂O = H₂CrO₄; 2CrO₃ + H₂O = H₂Cr₂O₇.
Web1. NH4+and S2− 2. Al3+and PO43− 3. Fe2+and PO43− Solution 1. Because the ammonium ion has a 1+ charge and the sulfide ion has a 2− charge, we need two ammonium ions to balance the charge on a single sulfide ion. Enclosing the formula for the ammonium ion in parentheses, we have (NH4)2S. The compound’s name is ammonium sulfide. WebChromium (III) hydroxide is a gelatinous green inorganic compound with the chemical formula Cr (OH)3. It is a polymer with an undefined structure and low solubility. It is amphoteric, dissolving in both strong alkalis and strong acids. [2] In alkali: In acid: It is used as a pigment, as a mordant, and as a catalyst for organic reactions. [3]
WebTo enter an electron into a chemical equation use {-} or e To enter an ion, specify charge after the compound in curly brackets: {+3} or {3+} or {3}. Example: Fe {3+} + I {-} = Fe {2+} + I2 Substitute immutable groups in chemical compounds to avoid ambiguity. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,
