You have 40.00 mL of a 0.300 M aqueous solution of the weak base C6H5NH2 (Kb = 4.00 x 10-10). This solution will be titrated with 0.300 M HCl. (a) How many mL of acid must be added to reach the equivalence point? (b) What is the pH of the solution before any acid is added? (c) What is the pH of the solution after 10.00 mL of acid has been added? (d) What is the pH of the solution...

Dont need (a) or (b) thank you
You have a 0.025 L solution of piperazine (perhydro-1,4-diazine), a weak dibasic base. The K, values for its conjugate acid are 4.65*10 and 1.86*10-10 (in a solution with an ionic strength of zero). You would like to know the concentration of your solution and decide to titrate with HCl. You make a 0.10 M solution of the acid and use methyl orange as an indicator. You reach the endpoint after adding 54.16 mL...

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...

second attempt. need asap please 2-4 sentences summarizing the article 4 interesting quotes from the article and 4 points explaining each quote In the first few years of the new millennium, at the height of the boom in the offshore call-center business, Tata Consultancy Services, the Indian technology-services giant, made the counterintuitive decision to divest its call-center operations. Why? Because although outsourced call centers were a fast-growing piece of its current business, TCS’s leadership had come to believe that they...

Part I— Just Bad Luck? Brrrring! Brrrring! Jane checked the caller ID on her phone. “Sam! Great!” she thought. It was always nice to get a call from her older brother. But a little twinge of worry tugged at her. It was just a couple of weeks ago that he had mentioned making an appointment with his doctor about some abdominal pain he had been having. “Hi Sam! It’s great to hear from you,” Jane answered. “Hi Jane. Well I...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
