3mL of (NH4)2S2O8 and 3mL of KI at 22 degrees C Time 0s, transmittance 87, absorbance 0.060 how do you find [I3-] ??
Added by Loser L.
Step 1
The reaction between (NH4)2S2O8 and KI produces I3- ions. The reaction can be represented as follows: 2KI + (NH4)2S2O8 → I2 + 2NH4I + K2SO4 I2 + KI → KI3 Show more…

Naphthalene $\left(\mathrm{C}_{10} \mathrm{H}_{2}\right)$ absorbs around $310 \mathrm{nm}$ in solution. The absorbance of a $1.00 \times 10^{-3} \mathrm{moldm}^{-3}$ solution is 0.29 in a $1.0 \mathrm{cm}$ cell. Find the molar absorption coefficient. At what concentration will the absorbance be $1.00 ?$ (Section 10.3 )
The compound $\mathrm{K}_{3}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]$ absorbs at $\lambda=418 \mathrm{nm}(\log \varepsilon=3.01) ;$ experiments are carried out in a cell of path length $1.00 \mathrm{cm}$. (a) Determine the absorbance of a solution of concentration $6.0 \times 10^{-4} \mathrm{mol} \mathrm{dm}^{-3} \cdot(\mathrm{b})$ What is the absorbance if the concentration is halved?
Calculate the $\mathrm{pH}$ of a household ammonia cleaning solution prepared by dissolving $\mathrm{NH}_{3}(g)$ in water to yield a $0.20 \mathrm{M} \mathrm{NH}_{3}(a q)$ solution at $25^{\circ} \mathrm{C}$.
