Answer:
1.3x10⁻⁸ mol/L
Explanation:
<em>0.0013μmol, Calculate concentration in mol/L</em>
<em />
To obtain concentration in mol/L we need to convert the μmoles to moles and mL to liters:
<em>Moles silver(II) oxide:</em>
0.0013μmol × (1mol / 1x10⁶μmol) = 1.3x10⁻⁹ moles
<em>Liters solution:</em>
100mL * (1L / 1000mL) = 0.1L
That means concentration in mol/L is:
1.3x10⁻⁹ moles / 0.1L =
<h3>1.3x10⁻⁸ mol/L</h3>
The balanced chemical equation is :
5P₄ + 36OH → 12HPO₃⁻² (aq) + 8PH₃ (acidic)
Here the oxidation number of P changed from 0 to -3 in PH₃ and increases from 0 to +3 in HPO₃⁻². When P₄ changes to PH₃ reduction reaction is taking place as there is addition of hydrogen and when P₄ changes to HPO₃⁻² oxidation takes place as there is addition of oxygen.
Thus clearly both reduction and oxidation are taking place.
Thus, we can infer that here P₄ is both oxidizing as well as reducing agent.
