what is the minimum temperature needed to dissolve 60 grams of K2CR2O7 in 100 milliliters of water?
See your earlier post.
To determine the minimum temperature needed to dissolve K2Cr2O7 in water, we can use the concept of solubility. Solubility refers to the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
In this case, we want to find the minimum temperature at which 60 grams of K2Cr2O7 can dissolve in 100 milliliters of water. The solubility of K2Cr2O7 in water is dependent on the temperature.
To find the minimum temperature, we need to find the solubility of K2Cr2O7 in water at different temperatures and see when it reaches or exceeds 60 grams/100 mL. This information can be found in a solubility chart or experimentally through a solubility experiment.
Let's say we have the solubility data for K2Cr2O7 at various temperatures and we find that at 80°C, the solubility of K2Cr2O7 in water is 70 grams/100 mL. This means that at 80°C or any temperature higher than 80°C, K2Cr2O7 will dissolve completely in 100 mL of water. Therefore, the minimum temperature needed to dissolve 60 grams of K2Cr2O7 in 100 mL of water is 80°C.
Please note that specific solubility data mentioned above is fictional and used here for illustrative purposes. You will need to consult a reliable source or conduct experiments to obtain actual solubility data.
