A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 80% pure antifreeze. The company wants to obtain 160 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed? Note that the ALEKS graphing calculator can be used to make computations easier. Water: gallons ? Premium antifreeze: gallons km faster than the...

Solution A has equal parts mixed of 1 M HF and 1 M NaCl. Solution B has equal parts of 1 M HCl and 1 M HF. Show your work, please use Ka = 6.8 x10-4 for HF . I'm not sure if I should use the Henderson-Hassalbalch Equation or the ICE table method. Also because the Ka is only 6.8 x10-4 I don't believe its possible to negate the the -x. Our professor told us it must be at least...
