Compare your results in 2. and 3. Are the base-neutralizing capacity and the acid-neutralizing capacity of the buffer similar? Explain why or why not.

For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.) 1. chromium(III) phosphate 2. silver carbonate Submit Answer Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water. chromium(III) phosphate silver carbonate Ksp = Ksp = Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s. A. CaSO4 B. CaF2 C. Cu(OH)2 D. Al(OH)3 Retry Entire Group 3 more group attempts remaining

Buffers will resist pH changes following the addition of acid or base within about +/-1 pH unit of the pka of a solution. True False

a). What are acids, bases and buffers?b) What are the different types of buffers? Describe the mechanism howbuffers resist pH change in a system.c) Elaborate all chemical reactions in the standardization of NaOH withKHP?d) Why do you need to use KHP in the standardization of NaOH?e) Why is phenolphthalein used as an indicator in this experiment?f) Compare and contrast: endpoint vs equivalence point.g) Discuss the role of acids, bases, buffers and pH in water qualitymonitoring and post-harvest fisheries.

The pH of the buffer solution is 4.0 while the pKa of the weak acid is 3.0. Compute for the molar part of the salt component     1 part     10 parts     0.1 part     0.01 part

I have seen other "experts" answer this question but i'm not understanding the process. Please write out the steps and why. And please explain why we use 0.100-x and x.

I need both solutions......

1. What would be the pH of buffer containing 137ml of 3.50M boric acid and 228ml of 1.90M lithium borate. The pKa of buffer system is 13.80.  solved answer pH= 13.76 2. What would be the pH of the buffer from question 1, after adding 84.5ml of 0.71 M KOH (strong base) to buffer? ??

(Please type answer note write by hand)

If you are given sodium acetate and asked to make a 250 mM acetate buffer and titrate it to a final pH of 4.76, will you have to add acid, base, or nothing in order to achieve the proper pH? Why? Please explain the “why” part of the question.         Please type answer note write by hend.
