1000 ml buffer is 0.175 M of HClO and 0.150M in HClO and the pH is 7.47
1. what is the pH when 10.00ml of 2.0M NaOH is added?
2. if you add 150mg of HBr what will be the new pH (assume no volume change). Molar mass of HBr is 80.91g/mol
sorry HClO it is 0.175 M and for NaClO it is 0.150

A)The amount of ClO- will increase B)The amount of HClO will increase C)The amounts of these components will stay the same D)The amount of HClO will decrease 2.) A 1L buffer solution is 0.175 M in HClO and 0.150 M in NaClO. What is the pH after addition of 0.10 mol HBr? pKa = 7.53 A)6.79 B)7.53 C)8.27 D)9.23
Consider the following two buffers: (i) 10.0 mL of a buffer that contains 0.10 M HClO and 0.10 M NaClO (ii) 10.0mL of a buffer that contains 0.050 M HClO and 0.10 M NaClO b.) 8 drops of 1.0 M NaOH (aq) is added to each of these buffers. 1.)Give the balanced net-ionic equation for the reaction that occurs when the NaOH (aq) is added. 2.)For which buffer (i or ii) does the pH change the greatest amount when the...
You are given a 100.0 mL buffer that is 0.50 M HClO and 0.76 M in NaClO (Ka for HClO= 3.5x10^-8). What would the pH of the buffer solution change to if we added 10.0 mL 1.00 M HCl?
22. A 100.0-ml buffer solution is 0.175 M in HCIO and 0.150 M in Nacio. a. What is the initial pH of this solution? b. What is the pH after addition of 150.0 mg of HBr?! c. What is the pH after addition of 85.0 mg of NaOH?
A buffer is prepared by combining 80.0 mL of 0.50M HClO and 40.0 mL of 1.0M NaClO. The Ka of hypochlourous acid is 3.5X10-8. a.) if one adds 0.080 mol of solid KOH to the solution, what will be the new pH? assume no change in volume. b.) If instead, one adds 20.0 mL of 1.0 M HCl to the orginal buffer, what will be the new pH?
The pH of 0.50 M HClO is 3.91. Calculate the change in pH when 1.29 g of NaClO is added to 18 mL of 0.50 M HClO. Ignore any changes in volume. The Ka value for HClO is 3.0 x 10-8.
You are asked to prepare 500. mL 0.150 M acetate buffer at pH 5.10 using only pure acetic acid (MW = 60.05 g/mol, pka = 4.76), 3.00 M NaOH, and water. How many grams of acetic acid will be needed to prepare the 500. mL buffer? Note that the given concentration of acetate refers to the concentration of all acetate species in solution. mass: DD What volume of 3.00 M NaOH, must be added to the acetic acid to achieve...
