a. A buffer solution is 0.480 M in HClO and 0.367 M in NaClO . If Ka for HClO is 3.5×10-8 , what is the pH of this buffer solution? b. A buffer solution is 0.481 M in H2S and 0.294 M in NaHS. If Ka1 for H2S is 1.0x10^-7, what is the pH of this buffer solution?
HClO is a weak acid (Ka= 4.0x10^-8 ) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.036 M in NaClO at 25 °C?
HClO is a weak acid (Ka=4.0×10−8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.014 M in NaClO at 25 °C?
HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.036 M in NaClO at 25 °C?
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
What is the pH of a 0.255 M aqueous solution of sodium hypochlorite, NaClO? (Ka for HClO = 3.5×10-8)
The pH of a 1.50 M solution of HClO is 3.67. pH = pKa + log [base] / [acid] a. Calculate the Ka of HClO. b. Calculate the pH and the percent dissociation of a 0.0100 M solution of NaClO.
