How do I know if an acid is weak

Postby J_Rodriguez_Dis2k » Fri Dec 04, 2015 1:53 pm

While i was doing the homework, some of the acid i did not know whether the acid was either strong or weak. How can i know for sure if an acid is either weak or strong?

You should memorize the strong acids and bases. Not only will this help you identify strong vs. weak acids, but it will help you know which ions (such as Na+, Cl-, etc.) will not affect pH. Ions associated with strong acids and bases do not participate alter the pH when added to water.

My TA said to just memorize the ones in the course-reader. So for strong acids, I would memorize HCl, HBr, HNO3, and H2SO4 as the strong acids. Weak acids would be H2CO3 and the C6H5COOH.

Strong bases would includes NaOH, CaO, Ca(OH)2 and Ba(OH)2
