The solubility of a substance, such as K2Cr2O7 (potassium dichromate), generally depends on various factors including temperature. To determine the temperature at which 55g of K2Cr2O7 would dissolve, we need the solubility data for K2Cr2O7 at different temperatures.
Unfortunately, I don't have access to real-time solubility data . However, I can provide some general information about the solubility of K2Cr2O7.
The solubility of K2Cr2O7 typically increases with temperature. In other words, as the temperature rises, more K2Cr2O7 can dissolve in a given amount of solvent.
To determine the exact temperature at which 55g of K2Cr2O7 would dissolve, you would need to refer to a solubility chart or consult a reliable source that provides solubility data for K2Cr2O7 at different temperatures.
