Taking logarithms and antilogarithms is necessary to solve many chemistry problems. For practice, complete the following table, where N is a number. N In N log N 6.19 4.016 -0.455

Part 1 of 2 Determine the pH of a 0.30 M NH3 solution. Be sure your answer has the correct number of significant digits. -5 Note: K for NH₂ is 1.78 × 10¯ pH = x10 X S

Try Again Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. A chemist prepares a solution of iron (II) chloride (FeCl₂) by measuring out 1.0 g of FeCl₂ into a 250. mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of C1 anions in the chemist's solution. Be sure your answer is rounded to 2 significant digits. 1.5 × 10 -2 mol L x10 X Ś

PART III: QUESTIONS        Question 1: a ‘law’ in science is a general statement that is the conclusion of multiple observations. Formulate a law that describes what happens when a metal chloride solution is mixed with a silver chloride solution. Question 2: Formulate a law that describes what happens when a metal chloride solution is mixed with a sodium phosphate solution.                   Question 3: If an aqueous solution of titanium chloride, which is clear and purple, is mixed with a silver nitrate solution, predict what precipitate will form. Question 4: If an aqueous solution of titanium chloride, which is clear and purple, is mixed with a sodium phosphate solution, predict what precipitate will form.

CHEMICAL REACTIONS Dilution A chemist must dilute 40.8 mL of 4.55 M aqueous zinc nitrate water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Be sure your answer has the correct number of significant digits. X S 0/3 (Zn(NO3)₂) solution until the concentration falls to 4.00 M. He'll do this by adding distilled
