Based on the attached table picture, please answer the attached question relating to the Table. Please briefly explain your answer. Please do not add a lot of details to the explanation, just briefly explain it. Thank you.In the laboratory, a general chemistry student measured the pH of a 0.386 M aqueous solution of ethylamine, C,H&NH, to be 12.094. Use the information she obtained to determine the K, for this base. K(experiment)- In the laboratory, a general chemistry student measured the pH of a 0.587 M aqueous solution of trimethylamine, (CH,),N to be 11.768. Use the information she obtained to determine the K, for this base. K,(experiment) =
- Using the table of the weak base below, you have chosen Pyridine as your weak base in the buffer solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.62 M in this salt. The desired pH of the buffer should be equal to 4.5. 3. Compute the concentration of the weak base in Molarity. (round off answer to 3 decimal places)Briefly summarize how the behavior of the buffer solution compares to the behavior of an unbuffered solution when a strong base is added. Justify your answer with your results.Objectives: To determine the solution if it is an acid, a base, or a buffer according to the pH value or changes in pH. Instructions: Read the given situations or observations and evaluate the given data. Determine the solution if it is an acid, a base, or a buffer. Observations: 1. The pH of solution A is 5.54, small amount of solution B is added into A and the resulting pH is 1.33. What is the solution A? What is the solution B? 2. The pH of solution C is 7.85, small amount of solution D is added into C and the resulting pH is 10.90. What is the solution C? What is the solution D? 3. The pH of solution E is 6.35. Small amount of solution F is added into E and the resulting pH is 6.33. What is the solution E? What is the solution F? Small amount of solution X is added to E causing an increase in pH to 6.37. What is the solution X?

- What is the relationship between the strength of an acid/base and its conjugate? A directly proportional B inversely proportional logarithmic parabolicPredicting acid or base strength from the conjugate Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions.
