Answer:
Concentration
Explanation:
Amount of substance concentration often called simply concentration, is a quantitative measure of the number of atom s per unit volume in a sample of a matter.
Answer:
4.48 - 6.48
Explanation:
A pH indicator works in a better way in a range of pH = pKa ± 1. That means we need to determine the pKa of the indicator propyl red to find the range over which it change its color. That is:
pKa = -log Ka
pKa = -log 3.3x10⁻⁶
pKa = 5.48
That means the range over propyl red will change from yellow to red or vice versa is:
4.48 - 6.48
Answer:
As the larger quantity
As the liquid which dissolves a solid
Explanation:
Solvent is the substance mostly in liquid form which dissolves the solute(e.g solid). The solvent also, is larger when compared to the solute.
Answer:
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
Example: For the given chemical equation:
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms which is a conjugate acid.
Thus the chemical symbol that is commonly used to represent a "proton" in the context of Bronsted-Lowry acids and bases is
