Final answer:
Converting CrX2OX3 to chromic acid involves understanding the redox reactions and carefully controlling reaction conditions such as pH. The direct conversion method suggested isn't clarified by the given reactions, so more information would be needed to develop an accurate procedure for the conversion.
Step-by-step explanation:
When attempting to produce more chromic acid, it's essential to take into account the chemistry involved in the conversion of chromium compounds. Looking at the reactions provided, particularly reaction (c), where Cr2+ is added to Cr2O72- in acid solution, we can deduce a method to increase chromic acid concentration. However, conversion directly from CrX2OX3 (where 'X' represents a placeholder for other elements or molecules) to chromic acid via addition to chromic acid and hydrogen peroxide (HX2OX2) is not clear from the given reactions. For a successful conversion, one would need to consider the oxidation states of chromium and the standard electrode potentials of the reactions involved. Typically, redox reactions, acid-base equilibria, and careful control of reaction conditions such as pH are utilized to facilitate such conversions.
