For TiCl4, delta H (not) is 54.3 kJ/mol and delta S (not) is 133 J/mol*K what is the boiling point of TiCl4 in degrees C?
Tell what type of chemical reaction is represented by the following chemical equation.
Show how a buffer system will not drastically change its pH by addition of a certain amount of a strong acid or base. Use 0.50 M buffer system and show how the pH will change upon addition of 10.0 mL each of ) 0.10 M of HCl or NaOH. Use any combin..
prepare 100 mL each of five standard solutions: 2.00 x 10-5, 5.00 x 10-5, 1.00 x 10-4, 2.00 x 10-4, and 5.00 x 10-4 M. These will serve as your analytical standards, which means that their phosphate concentrations must be precisely known.
