Question
When adding dimethylglyoxime to a basic solution, a student observes that formation of a red precipitate. What ion is indicated based on this test? Enter your answer as shown here, Ca^2+ as Ca 2+ or SO_4^2- as SO4 2- When a saturated MnCI_2 solution in 12M HCI are added to an unknown solution, a dark brown solution results. What ion is indicated based on this test? Enter your answer as shown here, Ca^2+ as Ca 2+ or SO_4^2- as SO4 2- A student collected the following data to determine the specifc heat of a metal sample. 50.0 g of metal were transferred from boiling water into a calorimeter containing 100g of H_2O at 22.3 degrees C. The temprature of the water rose to 23.5 degree C. Calculate the specific heat of the metal.Explanation / Answer
The ion is Ca2+ .It is brick red in color.
Thus, the ion indicated in the unknown solution is Ca2+
