Answer:
In a neutral solution the concentration of hydrogen ions is equal to the concentration of hydroxide ions
Explanation:
When:
[H⁺] > [OH⁻] the pH is acid, so the solution is practically acid.
When
[H⁺] < [OH⁻], the pH is basic, so the solution is practically basic
In neutral solutions:
[H⁺] = [OH⁻], so the pH is neutral (7)
pH > 7 → BASIC SOLUTIONS
pH < 7 → ACID SOLUTION
Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. They are classified as elements
How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
Concentration = 2.14 âś• 10-2 m
For [Br-], there are 2 ions so 2 x 2.14 x 10^-2 =4.28 x 10^-2
Ksp = [Pb][Br]^2 = 2.14 âś• 10-2 x (4.28 x 10^-2 )^2 = 39.20 x 10^-6
Ksp = 3.92 x 10^-5
