Following chemical reaction is involved upon titration of Ca(OH)2 with HCl,
Ca(OH)2 + 2HCl ↔ CaCL2 + 2H2O
Above is an example of acid-base titration to generate salt and water. Here, H+ ions of acid (HCl) combines with OH- (ions) of base [Ca(OH)2] to generated H2O
Given,
concentration of HCl = 0.0199 M
Total volume of HCl consumed during titration = 16.08 mL = 16.08 X 10^(-3) L
∴, number of moles of H+ consumed = Molarity X Vol. of HCl (in L)
= 0.0199 X 16.08 X 10^(-3)
= 3.1999 X 10^-4 mol
Thus, total number of moles of [OH-] ions present initial = 3.1999 X 10-4 mol
So, initial conc. [OH-] ion = ![\frac{number of moles of [OH-]}{volume of solution (L)}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bnumber%20of%20moles%20of%20%5BOH-%5D%7D%7Bvolume%20of%20solution%20%28L%29%7D%20)
=
![\frac{3.1999 X 10^(^-^4^)}{10 X 10^(^-^3^)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3.1999%20X%2010%5E%28%5E-%5E4%5E%29%7D%7B10%20X%2010%5E%28%5E-%5E3%5E%29%7D%20)
= 0.03199 M
Explanation:
When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride.
Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet.
Therefore, the chemical reaction equation will be as follows.
Answer:
That is called the synapse
