Answer:
Anion
Explanation:
Positive ions are called cations: they give out
Negative ions are called anions: they always receive
V is used to indicate Ecell ( just look at what measurement is simplified to V) <span />
Answer:
13.5g
Explanation:
Mass is defined as the measure of the amount of matter in an object. Its unit is kg or g.
Mass can be calculated using the formula:
m= d × v
where,
d= density
m= mass
v= volume
m= 2.5×5.4
m= 13.5g
In an acid base titration (for example a strong acid and strong base like HCl and NaOH), at equivalence point, the number moles of acid is equal to the number of moles of base.
HCl + NaOH ---- NaCl + H2O
Moles of Acid = Moles of Base
V(HCl) * M(HCl) = V(NaOH)*M(NaOH)
Now, beyond the equivalence point as more acid is added, the resulting pH will depend on the excess acid present.
