Explanation:
Because Water Reacts With Metal
Answer:
a. True
Explanation:
Yes, the titration curve can determine or can reveal the pKa value of a weak acid.
Titration is a scientific method to estimate the dissolved substance concentration, known as the titrand, in a known volume when it reacts with another chemical substance of known volume as well as concentration. The other substance is known as Titrant.
When a weak acid like acetic acid is titrated to a very strong base such as NaOH, the titration curve is obtained and the pH value is noted. But the titration curve of any weak acid shows a characteristic shape. At the end of titration, the acetic acid will convert into acetate ions.
pKa is the negative logarithm of the Ka of the acid. pKa is the pH of the acid where the concentration of the weak acid as well as the conjugate base is in equimolar concentration.
Hey there!
Lithium has 3 protons.
Assuming this is a neutral atom, that means it will also have 3 electrons.
Atomic mass is the sum of protons and neutrons. We have 7 total protons and neutrons, and 3 electrons.
7 + 3 = 10
The total number of subatomic particles is 10.
Hope this helps!
