Select the correct answers: “Ocean acidification is a process that occurs when atmospheric carbon dioxide dissolves in the ocean and is subsequently converted into (methane; carbonic acid; carbonate ions; sodium carbonite) . This then causes the pH of the ocean to (increase; decrease; fractionate; multiply) and become more acidic.”
If a person is taking part in strenuous activity or exercise, will this chemical equilibrium shift? If so, in what direction? Will the blood pH stay the same, increase, or decrease? Justify your reasoning and draw a concentration-time curve that represents this change
Using the table of the weak base below, you have chosen Methylamine 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 0.48 M in this salt. The desired pH of the buffer should be equal to 9.75. Values of K, for Some Common Weak Bases Conjugate Acid Name Formula 1.8 × 10-5 4.38 × 10-4 5.6 x 10-4 3.8 × 10-10 1.7 x 10-9 NH4 CH;NH3* NH3 CH;NH2 C¿H;NH2 CH;NH2 C;H;N Ammonia Methylamine Ethylamine Aniline C¿H§NH3* CH;NH;* C;H;NH+ Pyridine 3.

The pH scale depends on the value of Kw. What would the pH of neutral water be if the Kw was 5.54 x10-15? IMPORTANT: When entering your answer: •Enter the number only (no units) • Do not leave any spaces Use a leading zero before the decimal when necessary Report your number to 3 decimal places (regardless of the significant figures) • Correctly round your answer to the 3rd decimal place (allowed margin of error is only ± 0.001, so always use un- rounded numbers in your calculations) Examples: 0.123 or 9.876

You have chosen Methylamine 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 0.48 M in this salt. The desired pH of the buffer should be equal to 9.75. To prepare the buffer, a total volume of 550 mL is required. The stock solution of the weak base is available at 1 gallon with a concentration of 0.98 M. (Remember the lesson on dilution: C1V1=C2V2) 4. How many mL should be taken from the stock solution to prepare the desired buffer solution? (round off final answer to 1 decimal place)

I love you, Bartleby. Thank you for saving my life and career. I've learned so much!
First read the text sections 10.5 and 10.6 on pH. This is a Dry Lab since we cannot meet on Campus. After calibrating a pH meter you would have measured the pH of four different Basic Aqueous Solutions and examined the data for trends. You would have calculated the expected pH of each of the strong base solutions by assuming that for every NaOH formula unit that dissolves, one OH- ion is released. Thus, we can assume that the OH- Molarity equals the NaOH Molarity. Using the OH- Molarity and the water ionization equilibrium expression (Kw= 1.0 X 10 to the -14 power = H+ Molarity X OH- Molarity), we can calculate the H+ Molarity of the solution. Using the H+ Molarity, we can calculate the solution's pH. Thus a 1.0 X 10 to the 4 power NaOH solution has a pH of 10. The calculated pH value is arrived at as follows. By rearranging the water ionization equilibrium expression and plugging in the OH- Molarity, we can solve for H+ Molarity. H+ M = 1.0 X 10 to the -14 power divided by 1.0 X 10 to…
