Answer:

3 FeCl3 + H2S = 2 FeCl2 + S + 2 HCl

Explanation:

Fe goes form +3 to +2

S goes from -2 to 0

H and Cl are spectator ions

Fe3+ + 1e-= Fe2+

H2S = S + 2 H+ + 2e-

3 Fe3+ + H2S = 2 Fe2+ + S + 2 H+

3 FeCl3 + H2S = 2 FeCl2 + S + 2 HCl

Calculate the pH during the titration of 30.00 mL of 0.1000 M HCOOH(aq) with 0.1000 M NaOH(aq) after 29.3 mL of the base have be
pashok25 [27]

Answer:

3.336.

Explanation:

<em>Herein, the no. of millimoles of the acid (HCOOH) is more than that of the base (NaOH).</em>

<em />

So, <em>concentration of excess acid = [(NV)acid - (NV)base]/V total</em> = [(30.0 mL)(0.1 M) - (29.3 mL)(0.1 M)]/(59.3 mL) = <em>1.18 x 10⁻³ M.</em>

<em></em>

<em> For weak acids; [H⁺] = √Ka.C</em> = √(1.8 x 10⁻⁴)(1.18 x 10⁻³ M) = <em>4.61 x 10⁻⁴ M.</em>

∵ pH = - log[H⁺].

<em>∴ pH = - log(4.61 x 10⁻⁴) = 3.336.</em>
