검증된 단계별 안내1
Identify the elements present in the chemical formula NaCl. 'Na' stands for sodium, and 'Cl' stands for chlorine.
Understand that the formula NaCl represents a compound made of sodium and chlorine atoms combined in a 1:1 ratio.
Recall the common names of compounds formed by sodium and chlorine. Sodium combined with chlorine typically forms sodium chloride.
Recognize that sodium chlorite, sodium carbonate, and sodium chlorate have different chemical formulas: sodium chlorite is NaClO2, sodium carbonate is Na2CO3, and sodium chlorate is NaClO3.
Conclude that the chemical formula NaCl corresponds to sodium chloride, which is common table salt.
