Some MF2 is dissolved in water at 25oC to make a saturated solution. (M is a mystery metal - it's identity can be ignored.) Some of the solution is removed and tested, and it is found that the concentration of the fluoride ion is 1.2 x 10-4M. What is the Ksp of the MF2 at 25oC?
calculate the pH formed by mixing 100 mL of 0.20 M HCL with 50 mL of 0.30 M NaOH.
A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is.
Determine delta H of this reaction (kJ/mol H 2 SO 4 ) - When 24.4 mL of 0.500M sulphuric acid ,H 2 SO 4 is combined to 24.4ml of 1.00M potassium hydroxide KOH in a coffee cup calorimeter
