the Chlorine ion is attracted to the Sodium ion because chlorine ion is negative and the sodium ion is positive. positive and negative ions are always attracted. hence the two are attracted.

Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
