H3O+ eA mixture of solid chlorides was known to contain some or all of the following cations: Ag ,Al^3+Cr^3+,Ca^2+,and/or Zn^2+ . A student performed the following steps: 1.Water was added to the solid and the mixture was stirred well. After several minutes, some of the solid did not dissolve. The mixture was centrifuged and the supernatant was decanted from the solid (solution A). 2. NH4CI(aq) was added to solution A followed by NH3(aq) until the solution was basic to litmus. A gray-green precipitate was formed. The mixture was centrifuged and the supernatant (solution B) was decanted. The solid dissolved in NaOH(aq) and H2O2(aq) to form a light yellow solution. The solution was heated to dryness to remove the H2O2 and the solid was redissolved in HCI(aq). When ammonia was added to make the solution basic, a light yellow solution formed and no solid precipitated. 3. (NH4)2C204(aq) was added to solution B, and a precipitate formed.

- 1. What is the normality of an oxidizing agent of a solution of potassium dichromate (K2Cr2O7) containing 8.906 g per 200 mL in the presence of acid? (Cr2O7-2 + 6Fe+3 + 14H+ → 2Cr3+ + 6Fe3+ + 7H2O) NOTE: Present complete solution and also the corresponding units.Hardness in groundwater is due to the presence of metal ions, primarily Mg2+and Ca2+. Hardness is generally reported asppm (mg/L) CaCO3or mmol/L Ca2+. To measure water hardness, a sample of groundwater is titrated with EDTA, a chelating agent, in the presence of the indicator eriochrome black T, symbolized here as In. Eriochrome black T, a weaker chelating agent than EDTA, is red in the presence of Ca2+and turns blue when Ca2+is removed. A 50.00-mL sample of groundwater is titrated with 0.0850M EDTA. Assume that Ca2+accounts for all of the hardness in the groundwater. If 10.10 mL of EDTA is required to titrate the 50.00-mL sample, what is the hardness of the groundwater in molarity Ca2+and in ppm CaCO3?Complete and balance the following redox reaction in basic solution 2- 3c₂²- 1 + 2 (s) H* CIO₂(g) →CIO₂ (aq) + CIO3(aq) 3 4 H₂O Reset ( (1) LO 5 OH- H 6 (g) H3O+ 7 8 CI • x H₂O 9 (aq) S
