Interpretation:
The methods to separate the cations and anions in the given solutions are to be explained.
Concept introduction:
As per the solubility principle, based upon the solubility, and the ionic products of compounds, certain compounds get precipitated in certain solutions.
In a solution, precipitation reactions happen when cations and anions combine to form an insoluble ionic solid known as a precipitate.
An insoluble solid product that separates from a solution in achemical reaction is called as precipitate.
The reaction in which the precipitate gets formed is known as precipitation reaction.

- Write a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.arrow_forwardA soluble iodide was dissolved in water. Then an excess of silver nitrate, AgNO3, was added to precipitate all of the iodide ion as silver iodide, AgI. If 1.545 g of the soluble iodide gave 2.185 g of silver iodide, how many grams of iodine are in the sample of soluble iodide? What is the mass percentage of iodine, I, in the compound?arrow_forward1. Sometimes a reaction can fall in more than one category. Into what category (or categories) does the reaction of Ba(OH)2(aq) + H+PO4(aq) fit? acid-base and oxidation-reduction oxidation-reduction acid-base and precipitation precipitationarrow_forward
- Describe some physical and chemical properties of acids and bases. What is meant by a strong acid or base? Are strong acids and bases also strong electrolytes? Give several examples of strong acids and strong bases.arrow_forwardVitamin C is ascorbic acid, HC6H7O6, which can be titrated with a strong base. HC6H7O6(aq) + NaOH(aq) NaC6H7O6(aq) + H2O() A student dissolved a 500.0-mg vitamin C tablet in 200.0 mL water and then titrated it with 0.1250-M NaOH. It required 21.30 mL of the base to reach the equivalence point. Calculate the mass percentage of the tablet that is impurity.arrow_forwardChlorisondamine chloride (C14H20Cl6N2) is a drug used in the treatment of hypertension. A 1.28-g sample of a medication containing the drug was treated to destroy the organic material and to release all the chlorine as chloride ion. When the filtered solution containing chloride ion was treated with an excess of silver nitrate, 0.104 g silver chloride was recovered. Calculate the mass percent of chlorisondamine chloride in the medication, assuming the drug is the only source of chloride.arrow_forward
- Each box represents a tiny volume in an aqueous solution of an ionic compound. (For simplicity, water molecules are not shown.) Which box represents: (a) Na2CO3, (b) NH4NO3, (C) CaBr2? Explain your reasoning.arrow_forward3.101 Which (if any) of the following compounds are electrolytes? (a) glucose, C6H12O6, (b) ethanol, C2H5OH, (c) magnesium sulfide, MgS, (d) sulfur hexafluoride, SF6arrow_forwardBone was dissolved in hydrochloric acid, giving 50.0 mL of solution containing calcium chloride, CaCL2. To precipitate the calcium ion from the resulting solution, an excess of potassium oxalate was added. The precipitate of calcium oxalate, CaC2O4, weighed 1.437 g. What was the molarity of CaCl2 in the solution?arrow_forward
- Oranges and grapefruits are known as citrus fruits because their acidity comes mainly from citric acid, H3C6H5O7. Calculate the concentration of citric acid in a solution if a 30.00-mL sample is neutralized by 15.10 mL of 0.0100 M KOH. Assume that three acidic hydrogens of each citric acid molecule are neutralized in the reaction.arrow_forwardA solution of hydrogen peroxide, H2O2, is titrated with a solution of potassium permanganate, KMnO4. The reaction is 5H2O2(aq)+2KMnO4(aq)+3H2SO4(aq)5O2(g)+2MnSO4(aq)+K2SO4(aq)+8H2O(l) It requires 51.7 mL of 0.145 M KMnO4 to titrate 20.0 g of the solution of hydrogen peroxide. What is the mass percentage of H2O2 in the solution?arrow_forwardTwenty-five mL of a 0.388 M solution of Na2SO4 is mixed with 35.3 mL of 0.229 M Na2SO4. What is the molarity of the resulting solution? Assume that the volumes are additive.arrow_forward
