Precipitate Formation ne addition of hydrochloric acid to beakers containing solutions of either sodium chloride
a. Which beaker contains a precipitate?
b. What is the precipitate?
c. Write a chemical equation showing the reaction.
d. Classify the reaction.
(a)
Interpretation:
The beaker containing a precipitate needs to be determined.
Concept introduction:
The reactivity series of metals is as follows:
Lithium > Rubidium > Potassium > Calcium > Sodium > Magnesium > Aluminium > Manganese > Zinc > Iron > Nickel > Tin > Lead > Copper > Silver > Platinum > Gold
The metal higher on the series is the most active and will not be precipitated. The metal lower on the series is less active and hence will be precipitated.
Answer to Problem 112A
The beaker containing a mixture of
Explanation of Solution
Both HCl and NaCl are water soluble compounds. Because of this, adding HCl to NaCl will generate no precipitate. Hence, no products will be formed.
But addition of HCl to
So, the beaker containing a mixture of
(b)

Answer to Problem 112A
The precipitate on adding HCl to
Explanation of Solution
Addition of HCl to
(c)
Interpretation:
A chemical equation showing the reaction and formation of precipitate needs to be determined.
Concept introduction:
In a chemical reaction, the reactants are written on the left side of the equation and the product is written on the right side. The product and the reactants contain an arrow between them showing the proceeding of the reaction from the reactants to the products.
A chemical equation is balanced by balancing the number of moles of each element on the reactants and on the products according to the law of conservation of matter.
Answer to Problem 112A
The chemical equation of the reaction is,
Explanation of Solution
Addition of HCl to
The chemical equation can be given as,
(d)
Interpretation:
The type of the reaction needs to be determined.
Concept introduction:
In a chemical reaction, the reactants are written on the left side of the equation and the product is written on the right side. The product and the reactants contain an arrow between them showing the proceeding of the reaction from the reactants to the products.
A chemical equation is balanced by balancing the number of moles of each element on the reactants and on the products according to the law of conservation of matter.
Chemical reactions are classified according to the products they form as synthesis reaction, replacement reaction, oxidation reaction, combustion reaction, double-replacement reaction etc.
