TITRATION: I did the first page, but I need help with the rest;
I'm lost. I uploaded the first page because you need to reference
is for the preceding questions.
Pre-Lab Assignment: Titration (Week 11) Name: Group: Chapter 8 Section 7 in your lecture textbook covers the calculations needed for this week's lab. They are very similar to calculations we covered in Chapter 7. Complete the following before coming to lab. It will be GRADED! Given the balanced equation: HBraq)...
3. Calculate the molar concentration of an NOH us that required 15.81 ml to com pletely neutralise 0.509 g of KHP (Remember that the "pin KHP does not mean phos phorus. See the molecular structure and molar miss of KHP given earlier in the lab KHP(s) + NaOH(aq) NaKP(aq) + H,O(0) AGAGACOOOOOOOOOOOOOAAAA 4. Calculate the mass of KHP that will react completely with 25.00 mL of 0.1750 M NaOH. 5. Write the balanced equation for the reaction that occurs when...
Titration: Acids and Bases
2. How can you determine which acid is diprotic?
3. using the answers to questions one and two, which acid is
diprotic?
4. Which base has more hydroxide ions per molecule?
