by using a moving solvent on filter paper.
Explanation:
Answer:
2.1 M is the molarity of the HCl solution.
Explanation:

Molarity of HCl solution = 
Volume of HCl solution = 
Ionizable hydrogen ions in HCl = 
Molarity of NaOH solution = 
Volume of NaOH solution = 
Ionizable hydroxide ions in NaOH = 
(neutralization )


2.1 M is the molarity of the HCl solution.
Well ionic compounds are brittle because similar charges repel, which causes them to break usually occurring when a force is applied, like a hammer strike.
