WebPhET: pH Scale. Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH.

WebMar 15, 2014 · According to the collision theory, there are two ways to increase reaction rate: increase the frequency of collisions, and increase the fraction of collisions that are effective. If you speed up the particles by increasing temperature, there is a greater likelihood that they will bump into one another, and the reaction rate goes up.
