A solution has a pH of 1. Which of the following best describes the solution?

If the concentration of OH- ions in a solution is 4.0 x 10-11 M, what is the concentration of H3O+?

Predict whether or not the following compound will be soluble or insoluble in water.  

Use the equations below to calculate the concentration of the ion and the pH of the solution. Record both answers to the tenths.  Determine if the solution is acidic, basic or neutral.  (H3O+) x  (OH-) = 1.00 x 10-14 M2                 pH  = -log(H3O+) Given:  (H3O+) = 2.7 x 10-10 M             (OH-) = [OH]              pH  =  [ph]     acidic, basic, or neutral? = [acid]

If the concentration of OH- ions in a solution is 4.0 x 10-11 M, what is the concentration of H3O+?

What color is phenolphthalein in an acid?

Use the equation below to solve the following problem.   What is the molarity of a solution that contains 1.54 moles of solute in 250 mL of solution? To receive full credit:  You must use the math equation editor in the tool bar to insert the final equation (with numbers and units) that you used to solve the problem.  Be sure to include the answer.  Or, solve the problem on your own paper and upload the picture into the Unit 3 Exam pictures dropbox immediately after submitting the exam.
