Question
Chapter 4, Problem 30A
Interpretation Introduction
Interpretation:
The use of NaCl paste in the ECG have to be described.
Concept Introduction:
An electrocardiogram (ECG) records the electrical signal from the heart.
Expert Solution & Answer
Answer to Problem 30A
Melted NaCl paste was used to coat during ECG for a cardiac patient. This is because the melted NaCl or NaCl in the solution dissociate to give Na+ and Cl- ions and these ions are good conductors of electricity. An
Explanation of Solution
Free ions in the solution conduct electricity. In solid NaCl, the ions are tightly bound and do not conduct electricity. Melted NaCl paste was used to coat during ECG for a cardiac patient. This is because the melted NaCl or NaCl in the solution dissociate to give Na+ and Cl- ions and these ions are good conductors of electricity. An electric current can pass through the melted salt. This paste carries the electrical signal from heart to the machine.
