60 mL of 0.1M HOAc (Ka= 1.75X105) was titrated with 0.1M NaOH. a) What is the pH after addition of: (0.0 ml, 60.0 ml and 75 ml) of NaOH.

K2HPO4-KH2PO4 buffer solution with water, vinegar, 0.85 M Na2CO3 sodium carbonate K2HPO4-K3PO4 buffer solution with water, vinegar, 0.85 M Na2CO3 sodium carbonate For each buffered solution from above: A.) Describe how the pH changed for added vinegar relative to cabbage indicator. B.) Describe how the pH changed for added sodium carbonate relative to cabbage indicator. C.) Describe the pH of the three solutions (using numbers from tabs and color chart). D.) Calculate the pKa of each buffered solution. E.) Compare the pKa calculated to the pH found using the tabs (close, very different?) I am having trouble understanding this problem if someone can help me walk it through. thank you very much

Which of these apply to the Image (attached)? There should be 4 total answers: A. High End pH B. High Initial pH C. Vertical Line with Equivalence Point Tall D. Equivalence Point Not at pH 7 E. Equivalence point at pH 7 F. low end pH G. low initial pH H. Vertical Line with Equivalence Point Short   Using the info identified above, what type of analyte and tirant combo are in the image. Options for Analyte and Titrant: - Weak base - Strong Acid - Strong Base - Weak Acid

Please provide detailed solution and give the explanation of the concept....
