Calculate the volume of 8.87×10-2 m calcium hydroxide required to neutralize 15.0 ml of a 0.389 m hydrobromic acid solution. ml

Answer : The volume of calcium hydroxide is, 32.89 ml

Explanation :

Using neutralization law,

where,

= basicity of an acid = 1

= acidity of a base = 2

= concentration of hydrobromic acid = 0.389 M

= concentration of calcium hydroxide = 0.0887 M

= volume of hydrobromic acid = 15 ml

= volume of calcium hydroxide = ?

Now put all the given values in the above law, we get the volume of calcium hydroxide.

Therefore, the volume of calcium hydroxide is, 32.89 ml

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
