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
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.
HA = Acid
= Base
= Conjugate base
= Conjugate acid
For example:
Sulfuric acid dissociating in its solution to form conjugate base and conjugate acid.
Sulfuric acid = Acid
= Base
= Conjugate base
= Conjugate acid
The substance that is in the smaller amount is the solute. so yes, the answer is true.
Answer:
120 grams
Explanation:
Data:
Volume = V= 2 L
Molarity = 1.5 M
Molecular masses:
Na = 23, O= 16, H=1
Total molecular mass =M= 23+16+1 = 40
mass = m = ?
To find the mass we need to find moles from molarity formula:
Molarity = n/V
n= Molarity x V
= 1.5 x 2
n= 3 moles
Now we can find mass:
number of moles = given mass / molecular mass
n = m/M
m= n x M
= 3 x 40
m = 120 grams
