17.5 mL of 0.1000M NaOH was required to neutralize 25.0 mL of HCl. What was the molarity of the HCl?

The molarity of is 0.07 M

Explanation:

According to the neutralization law,

where,

= basicity = 1

= molarity of solution = ?

= volume of   solution = 25.0 ml

= acidity of = 1

= molarity of solution = 0.1000 M

= volume of   solution = 17.5 ml

Putting in the values we get:

Therefore, molarity of is 0.07 M

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
