This
is a neutralization, which means we are mixing a base with an acid until the
mixture becomes neutral. We add more HI to the NaOH until the number of acid
equivalents is equal to the number of base equivalents. We can calculate the
acid equivalents using normality and volume, and the same with base equivalents.
A =
acid equivalents = normality*volume (in the acid solution)
B =
base equivalents = normality*volumen (in the base solution)
A =
B
NA*VA
= NB*VB
HI
is an acid which releases only 1 acid equivalent per molecule, so its molarity
is equal to its normality.
NaOH
is a base which releases only 1 base equivalent per formula unit, so its
molarity is equal to its normality.
MA*VA
= MB*VB
We’re
trying to find out NaOH molarity, which is equal to the NaOH normality.
MB
= MA*VA/VB
DATA:
MA
= 3.0 M
<span>The
volumen of HI used can be calculated by subtracting the
final volume of the burette to its initial volume (the final volume is smaller,
as we have taken some volume away)</span>
VA
= V0-Vf = 0.7 ml - 0.2 ml = 0.5 ml
VB
= V0-Vf = 47.6 ml - 37.5 ml = 10.1 ml
MB
= 3.0M*0.5M/10.1M = 0.149 M
Answer:
The answer is D) Electrolytic cell
Explanation:
An electrolytic cell is a device used for the decomposition by the electrical current of ionized substances called electrolytes.
When the two electrodes are connected by a wire, electrical energy is produced, and a flow of electrons takes place from the electrode.
These cells are the closest thing to a galvanic battery.
Answer:
txt and I'm going out of the way for a bit but it will probably take 6th and 6th and then we will have a lot and we will have a lot and we will make it work and I'm not
It is a base due to the color change!
Hope this helps!
Mark me brainliest please...
By not letting the sick run while doing other things like scrubbing dishes..
