Given only NaHS and HCl, How many mL of 1.00 M HCl should be added to a 50.0 mL solution that has1.00 mmol of NaHS to create a buffer solution with pH of 7.022. Equilibrium constants of H2S: Ka1 = 9.5 x 10-8 Ka2 =1 .3 x 10-14
Calculate the concentrations of the weak acid and conjugate base for the best possible buffer at pH 3.50 knowing that the concentration of the more concentrated species between the two will be 0.2 M. Choose the buffer system you think would be best between the following three. You will need to look up literature values for the Ka/pKa on your own. Remember that a strong buffer has similar concentrations of the buffering components. Formic acid/formate Acetic acid/acetate Hypobromous acid/Hypobromite
Phenol red is a common acid-base indicator. It has a pKa equal to 8.000. It's undissociated form is yellow and its anionic form is violet. What color would a solution containing phenol red solution if the pH is 7.50? yellow yellow-orange red-orange red-violet violet
One Erlenmeyer contains 50 mL of 0.1 M Na2CO3 solution, the other Erlenmeyer contains 50 mL of 0.1 M NaHCO3 solution. Answer the following questions when both solutions are titrated with 0.1 M HCl (F=1) solution separately: a) How much mL will be consumed if the phenolphthalein indicator is used? b) How much mL will be consumed if the methyl orange indicator is used? please explain than solve
Reaction: NaHCO3(aq) + HCl(aq) ® NaCl(aq) + CO2(g) + H2O(l) Methyl orange is a pH indicator. It is yellow above pH 4.4, orange between pH 4.4 and 3.2 and red below pH 3.2. NaHCO3 is a weak base and it must be acidified to about pH 4 to completely neutralize it. Why did you test the reaction mixture with this indicator before you began the evaporation step?
