Define concentrated and Dilute Alkalis with example
Answers
Explanation:
The strength of an acid, called its acidity, is an expression of the H+ concentration for a given volume of a solution. Assuming we have a solution with water, there is always some amount of H+ around, even in basic substances like lye or window cleaner. When put in water, a base creates the hydroxide ion, OH-.
In order to determine the strength of an acid solution, we can mathematically define the acidity in a few different ways. We could also talk about the basicity of a solution, but let's focus on acids.
Mass Percent
The percentage of something is simply the ratio of a piece of the whole relative to the whole, multiplied by 100. The mass percent of an acid is
null
Mass percent is often what the manufacturer of the acid or base puts on the bottle.
Density
The density of a sample of any substance is its mass divided by the volume of the sample:
null
For example, the density of an acid sample with a mass of 25 g and a volume of 13 mL is
null
Density tells us how closely the particles in a substance are packed together. When particles have a high density, they can interact more strongly with nearby particles.
Molarity
