Answer #1

ANSWER:

As per the given information

Note :

A precipitation reaction is the type of chemical reaction which involves the combination of soluble cations and anions to form insoluble material or product called "precipitate".

By this we can say that

The formation of this insoluble material is an example of a precipitation reaction.

Option "B" is right

Thanks..STAY SAFE

    "Hard" water contains mainly salts of Ca2+ and Mg2+, both of which form many insoluble salts. You have a water sample and need to determine whether it contains Ca2+ and/or Mg2+. When you add ammonia to the solution, followed by ammonium chloride and ammonium oxalate, a white precipitate of CaC2O4 should form if Ca2+ is present. What is the purpose of adding the ammonium chloride to the reactant mixture? a. The chloride ion helps to form the calcium chloride precipitate....

    Hard water normally contains mineral ions, such as Ca2+ and Mg2+ ions, from minerals that dissolved in the ground water. For water of low hardness, the concentration of Ca2+ ions is usually expressed as ppm CaCO3 in the water sample. Parts per million (ppm) is defined as one part of solute mass per 1,000,000 parts of solution mass, as shown in the following equation. Please note, the unit of denominator and numerator needs to be the same. Since ppm expresses...

    Hard water often contains dissolved calcium ion and magnesium ions. One way to soften water is to add phosphate salts. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. Suppose that a solution is 5.5×10−2 M in calcium chloride and 9.5×10−2 M in magnesium nitrate. What mass of sodium phosphate would have to be added to 11.5 L of this solution to completely eliminate the hard water ions? (Assume complete reaction.)
