150 APPENDIX D 



In an acid solution, pH is less than 7; in an 

 alkaline solution it is more than 7. 



pH 0: the solution contains 1 mole (H+) per 

 liter. Explain. 



pH 14: the solution contains I mole (OH") 

 per liter. Explain. 



What is the concentration of (H+) in a solu- 

 tion of pH 7.35? 9.73? 



What is the approximate pH of a solution 

 containing: 0.03 moles per liter of hydrochloric 

 acid? 0.0007 moles per liter of potassium 

 hydroxide?
