Answer:
The correct answer is option a.
Explanation:
Equilibrium concentration cadmium ions = ![[Cd^{2+}]=0.0585 M](https://tex.z-dn.net/?f=%5BCd%5E%7B2%2B%7D%5D%3D0.0585%20M)
Equilibrium concentration fluoride ions = ![[F^{-}]=0.117 M](https://tex.z-dn.net/?f=%5BF%5E%7B-%7D%5D%3D0.117%20M)
Molar solubility is the maximum concentration of salt present in water in ionic form beyond that no more salt will exist in its ionic form and will settle down in bottom of the solution.
The molar solubility of the solid cadmium fluoride = 0.0585 M
..[1]
Due to addition of sodium fluoride will increase concentration of fluoride in the solution.And due to common ion effect the equilibrium will shift in backward direction in [1], that is precipitation of more cadmium fluoride.
Hence, decrease in solubility will be observed.
Answer:
Water and Salt
Explanation:
A neutralization reaction occurs when an acid and a base react to produce water and a salt, and it entails the formation of water from the mixture of H+ and OH- ions.
Answer:
The "2" applies only to the sodium, and sugar is a substance
Explanation:
The amount of atoms in an element are written using small letters after the element they refer to.
A. True
Because Each element is made up of unique type of atom that has very specific properties
Answer:observation
Explanation:
this is the answer because they saw it they know it is there. the flowers are pink and they saw that that’s what an observation is so the answer is an OBSERVATION
