10.0 mL of 0.0400 M KBrO3 and 10.0 mL 0.100 M HCl is mixed with 10.0 mL of 0.0100 M KI, 10.0 mL 0.00100 M Na2S2O3, 1.0 mL of sta
Oliga [24]

Answer:

0.0196

Explanation:

The Total volume of the solution = Volume of (KBrO_3 + HCl + KI +Na_2S_2O_3 + Starch + H_2O)

= 10 mL + 10 mL + 10 mL+ 10 mL + 1 mL + 10 mL

= 51 mL

The concentration of  [H^+] = \dfrac{ mL \ used \times 0.1 \ M}{total \ volume}

= \dfrac{10 \ mL \times 0.1 M}{51 \ mL}

= 0.0196

Which acid is the best choice to create a buffer with ph= 3.19?
Crazy boy [7]
<span>The best choice is hypochlorous acid nitrous acid (HNO2) because it has the nearest value of pK to the desired pH.
pKa of </span>nitrous acid<span> is 3.34 
If we know pKa and pH values,  we can calculate the required ratio of conjugate base (NO2⁻) to acid (HNO2) from the following equation:
pH=pKa + log(conc. of base)/( conc. of acid)
</span><span>3.19=3.34 + log c(NO2⁻)/c(HNO2)
</span><span>3.19 - 3.34 = log c(NO2⁻)/c(HNO2)
-0.15 = log c(NO2⁻)/c(HNO2)
c(NO2⁻)/c(HNO2) = 10⁰¹⁵ = 1.41
