what is the ph of a solution prepared by dissolving 0.50 mol of acetic acid and 0.2 mol of sodium acetate in water and adjusting the volume of 0.5L if the pka for acetic acid is 4.75. of 0.010 mol of sodium hydroxide is added to the buffer solution from part (a), determine the ph of the new solution
Review Problem 16.065 A sodium hydroxide solution is prepared by dissolving 9.0 g NaOH in 3.00 L of solution. What is the molar concentration of OH in this solution? What are the pOH and the pH of the solution? What is the hydrogen ion concentration in this solution? [OH-] = рон = pH = [H+] = x 10
What is the molarity of sodium hydroxide (NaOH) in a solution prepared by dissolving 100 g of the solute into 1000 mL of solution?
1.) What is the molarity of a potassium hydroxide solution prepared by dissolving 2.74 g KOH in 4.2 mL of water? 2.) How many grams of sodium hydroxide are delivered by 6.8 mL of a 10 % solution in water? 3.) Hydrogen chloride (a gas) is dissolved into water to create hydrochloric acid, and therefore is a solution. Commercially available concentrated hydrochloric acid is sold as a 35 - 37 % solution. What molarity does this equate to? 4.) How...
What is the pH at 25°C of a solution that results from mixing equal volumes of a 0.0500 M solution of acetic acid and a 0.0374 M solution of sodium hydroxide? The pKa of acetic acid is 4.74. Express the pH to at least two decimal places.
a. What is the pH of 16.13 L solution if 19.89 g of sodium hydroxide are dissolved inside? b. What is the pH of a 0.045 M HCl solution?
ACDS AND BASES Calculating the ph of a strong base solution A chemist dissolves 582. mg of pure sodium hydroxide in enough water to make up 100 mL of solution. Calculate the pH of the solution. (The temperature of the solution is 25 °C.) Round your answer to 3 significant decimal places X
A chemist must prepare 750.0 mL of sodium hydroxide solution with a pH of 13.70 at 25 °C. She will do this in three steps: • Fill a 750.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid sodium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step. Round...
A chemist must prepare 650.0mL of sodium hydroxide solution with a pH of 12.90 at 25°C. He will do this in three steps: Fill a 650.0mL volumetric flask about halfway with distilled water. Weigh out a small amount of solid sodium hydroxide and add it to the flask. Fill the flask to the mark with distilled water. Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step. Round your answer to 2 significant digits.
A student wants to make a standard solution of sodium hydroxide. She realizes it is not wise, having calculated the mass of sodium hydroxide, to weigh it out and dissolve it in the appropriate volume of water. The concentration of the sodium hydroxide solution will not be the value expected. § Give TWO reasons why a standard solution of sodium hydroxide cannot be made in this way. § What are the correct method to prepare the standard solution of sodium...
