1. A student in the lab places drops of the indicator phenolphthalein a solution. The color of the clear solution becomes pink. a) Compare the hydroxide ion concentration to the hydronium ion concentration in the solution. b) The student adds another solution and the phenlolphthalien in the solution changes the color of the solution from pink to a clear solution. Describe how the hydronium ion concentration changed (increased, decreased or remained the same). Explain your answer. Answer: Explanation:
