Hint In the part of general chemistry, the concept of writing a balanced chemical equation when two or more reactants react to give new products and the products written according to the basic rule will lead you to the required answer.

Complete step – by – step answer:
From the previous chapters of organic and inorganic chemistry, we have studied how to write a balanced chemical equation accordingly from the data given and also several related terminologies.
Let us now focus on writing the required chemical equation which is based on the data given that is reaction of sodium carbonate with copper sulphate.
- Sodium carbonate is the common chemical which has the common name washing soda and this compound is white crystalline in nature.
- Copper sulphate crystals when added to water form aqueous solution which is blue in colour.
So when the sodium carbonate chemical is added to this aqueous solution of copper sulphate, the colour of the aqueous solution changes to the pale green which is in the form of precipitate.
Thus, by writing the balanced chemical equation, we shall find the precipitate formed.
Na2CO3+CuSO4CuCO3+Na2SO4
Thus, the precipitate formed will be the copper carbonate.

Hence, the correct answer is option C) Basic copper carbonate is precipitated.

Note: It is important to note that balancing a chemical reaction plays a major role in such types of questions and slight confusions can lead to a different set of products. so you should be thorough with the concept of the balanced chemical equations.
