3. Using Equation 18-5 and the pKIn value you found, determine the ratio [In-]/[HIn] at the pH in the middle of the range you studied (i. e., pH = 6.0 for bromocresol purple, pH = 7.0 for bromothymol blue, and pH = 7.7 for phenol red). Show how you accomplished this. Draw a conclusion about the relative concentrations of In- and HIn at pH values very close to the pKIn of the indicator.

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?
