    資料紹介

    Object;
    Part A - Determine the changing color of the indicator(nethyl orange) in the
    reaction(HCL + NaOH) and with water..
    Part B - Determine the reaction to form Iron Thiocyanate.

    Discussion;

    Part A – Q.1 addition of acid --- NaOH + HCL ⇔ NaCl + H2O (orange color)
    Part A – Q.2 addition of acid --- NaCl + H2O ⇔ NaOH + HCL (reddish color)
    Part A – Q.2 Changing color
    Part A – Q.3 addition of acid --- reaction shift right
    Part A – Q.2 addition of base --- reaction shift left
    Part A – Q.4 When we added base to acid, color became light orange. And when we added acid to
    Part A – Q.4 base, color turned reddish color.

    Part B – Q.1 FeCl3 + KSCN ⇔ FeSCN + KCl3 (darkred)
    Part A – Q.2 There were no changes.
    Part A – Q.3 There were no changes.
    Part A – Q.4 Became clear. (orange, darkred precipitate)
    Part A – Q.5 FeCl3 + NaOH → Fe(OH) 3 + NaCl3
    Part A – Q.6 Became clear. (whitish precipitate) AGSCN
    Part A – Q.7 FeSCN + AgNO3 → AgSCN + FeNO3
    Part A – Q.8 If a system at equilibrium, and if we change concentration, pressure or temperature,
    Part A Q.8 reaction shift to the direction which we changed concentration, pressure or
    Part A Q.8 temperature.
