Buffers
● Weak Acid and a Weak Base which are a conjugate acid/base pair - animation - interactive (McGraw-Hill) Visit Site
● Add equal amount of NaOH or HCl (any amt you choose) to water and a buffered soln, can also change indicator, and plot results (applet) Visit Site

pH - Ch 19.3
● Animation - pH meter allows testing pH of acids, bases, salts and unknown, different concentrations (Flash) (I State U) Visit Site
● pH slider shows substances with various pH values – interactive– John Kyrk pH scale, slider can move to show you substances that have certain pH values Visit Site
● Sodium - Scroll down to "Sodium Party". Lots of videos & background how Na reacts with water and also O2. These guys are crazzy!!! Visit Site

pH Indicator
● Carbon Dioxide Behaves as an Acid in Water, uses bromothymol blue as indicator - movie Visit Site

Titration
● Acid/Base Titrations animations, titrate to end-point (I State U) Visit Site

Weak vs Strong
● Animation shows ionization of HF and HCl (McGraw-Hill) Visit Site
