Answer:
K⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻ (aq) → KCl (aq) + H⁺ (aq) + F⁻ (aq)
Explanation:
KF (aq) + HCl (aq) → KCl (aq) + HF (aq)
KF (aq) → K⁺ (aq) + F⁻ (aq)
HCl (aq) → H⁺ (aq) + Cl⁻ (aq)
KCl (aq) → K⁺ (aq) + Cl⁻ (aq)
HF (aq) → H⁺ (aq) + F⁻ (aq)
Hydrochloric Acid (HCl) is a strong acid when it is present in the concentrated form but when it is dissolved in water (
) the atoms of this compound dissociates into its respective ions as shown below:
When we add HCl to any complex in its concentrated form the complex does not react at all but when its diluted to 6M and is kept for many hours, the complex reacts slowly. For eg:
![[Co(NH_3)_6]^3^+(aq.) + HCl(aq.) \rightarrow [Co(NH_3)_5Cl]^2^+(aq.) + NH_4^+ (aq.)](https://tex.z-dn.net/?f=%5BCo%28NH_3%29_6%5D%5E3%5E%2B%28aq.%29%20%2B%20HCl%28aq.%29%20%5Crightarrow%20%20%5BCo%28NH_3%29_5Cl%5D%5E2%5E%2B%28aq.%29%20%2B%20NH_4%5E%2B%20%28aq.%29)
As seen from the above reaction it can be seen the positive charge on the complex is reduced by 1 unit because one 
ion gets attached to the centre metal atom, therefore we can conclude that the charge on complex gets reduced by 1 unit when HCl reacts with the complex.
Answer:
190n
Explanation:
190 190 and because it is easy to understand if you didn't understand my answer ask any man
Answer:
N and P
Explanation:
Anion:
When an atom gain the electrons anion is formed. The negative sign shows that atom gain electron because number of electron are greater than protons or we can say that negative charge becomes greater than positive charge.
Cation:
When atom lose electron cation is formed. The atom thus have positive charge because number of positive charge i.e protons are increased are greater than negative charge or electron.
In given problem N and phosphorus both can gain three electrons which means negative charge becomes greater that's why the extra electron gained by atoms are written as -3 and both form anion with charge -3.
while Al form cation with charge +3 Mg form cation with charge +2 and iodine and bromine both form anion with charge of -1.
