Suppose you add 20 drops of 0.2M NaOH to 17 drops of 0.2M HCl.  Phenolphthalein has been added to the HCl.  What color do you suspect the resulting solution will be?  Why?  I think that I need to find the pH, because phenolphthalein turns pink at pHs 7-10, and NaOH is a base and HCl is an acid.

calculate the PH after 15.0 ml of 0.10M NaOH has been added to 100.0 ml of a butter that is 0.50 M in HOCL and 0.40M in NaCL, (ka for HOCI= 3.5X10^-8

Write out a chemical equation. (The chemical equation, for example, is NaOH + HCl ® HOH + NaCl.) Explain what the equivalence point is, what the pH is at the equivalence point in this reaction and why the pH is what it is.

what is the pH of a solution prepared by mixing 50.0 mL of 0.125 M amonia and 25.0 mL of 0.100 M hyrogen chloride (The acid dissociation constant of amonnium ion is 5.70x10-10)

Calculate the pH function of a solution obtained by adding 10 milliliters of 0.1 M acetic acid to 20 milliliters of 0.1 M sodium acetate. If you knew that the acid's dissociation constant is 1.75 * 10-5 5.06 4.76 6.80 O O

Please don't provide handwriting solution

Calculate the pH of the solution that results following addition of 30 mL of 1 M NaOH to 40 mL of 1 M NH4Cl.

Please finish both parts and show all steps thank you.

by the addition of strong base in a buffer, pH of the solution is maintained by?  1- Shifting equilibrium toward right side  2- Shifting equilibrium toward left side  3- by producing weak acid and more H ions  4- by producing conjugate base and more OH ions

10 An analytical chemist is titrating 120.4 mL of a 0.5800M solution of piperidine (C5H₁NH) with a 0.7600M solution of HNO3. The pK, of piperidine is 2.89. Calculate the pH of the base solution after the chemist has added 64.0 mL of the HNO3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added. Round your answer to 2 decimal places. pH = 0 Ś
