Suppose you carry out a titration involving 3.00 molar HCl and an unknown concentration of KOH. To bring the reaction to its end point, you add 35.3 milliliters of HCl to 105.0 milliliters of KOH. What is the concentration of the KOH solution?

The concentration of the KOH solution is 1.01 M

Explanation:

According to neutralization law:

where,

= basicity of = 1

= acidity of KOH = 1

= concentration of HCl = 3.00 M

= concentration of KOH = ?

= volume of HCl = 35.3 ml

= volume of KOH = 105.0 ml

Putting the values we get:

Thus the concentration of the KOH solution is 1.01 M

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
