Concept explainers
What are the correct coefficients (reading from left to right) when the chemical equation is balanced?
_PCI3(/) + _H2O(/) → _H3PO3(aq) + _HCl(aq)
1, 3,2,1
1: 2, 1, 1
3, 6, 1,9
1: 3, 1, 3
Interpretation: To find out the correct coefficients when the chemical equation is balanced.
Concept introduction:
In chemistry, the coefficient is the number present in front of the chemical formula in a chemical equation.
Correct answer: The correct answer is option (d)
Explanation of Solution
Reason for the correct answer: The unbalanced equation:
To balance O atoms place the coefficients
To balance Cl atoms place the coefficients
This is the balanced equation because
The correct coefficients from left to right in the balanced equation will be
Reason for incorrect answer: Option (a) coefficient
Option (b) coefficient
Option (c) coefficient
Thus, option (d) is found to be correct answer and options (a), (b) and (c) found to be wrong answers.

- An unknown solid acid is either citric acid or tartaric acid. To determine which acid you have, you titrate a sample of the solid with aqueous NaOH and from this determine the molar mass of the unknown acid. The appropriate equations are as follows. Citric acid: H3C6H5O7(aq) + 3 NaOH(aq) 3 H2O(l) + Na3C6H5O7(aq) Tartaric acid: H2C4H4O6(aq)+ 2 NaOH(aq) 2 H2O(l) + Na2C4H4O6(aq) A 0.956-g sample requires 29.1 mL of 0.513 M NaOH to consume the acid completely.
