H2O is the Bronsted-Lowry base because it accepts the hydrogen ion to become H3O after the reaction is complete.
Answer:
Less than
Explanation:
According to the question, the drop counter is counting four out of five drops of base added to the HCl. So when the titration will reach to the end point the volume of Base recorded will be less than the actual volume of the base dropped in the solution.
We will use law of equivalence for the calculation of concentration of HCl,
Where, 
and 
are molarity and volume of HCl and 
and 
are molarity of volume of the base added.
Thus concentration of HCl will be calculated as,
As the recorded is less than the actual amount present in the solution, the calculated value of concentration of HCl will also be less than the actual.
It’s c had this problem last week
The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
Answer:
Ammonia gas(an alkaline gas with characteristics of choking or irritating smell) is not liberated when 6mole of HCl is added to the solution instead of 6mole of NaOH, to test for the presence of ammonium ion in the solution
Explanation:
As expected, when testing for ammonium ion in a solution (precisely ammonium salt solution), Sodium Hydroxide (NaOH) is required as the test reagent.
When NaOH is added to the solution, A gas with characteristics of choking or irritating smell is liberated.
This gas turn red litmus paper blue.
This liberated gas is an alkaline gas, which is confirmed as an ammonia gas(NH3).
If HCl is added instead of NaOH, the ammonia gas will not be liberated, which indicates that the test reagent used is wrong.
