Which is more soluble LiCl NaCl KCl RbCl?
The covalent character of any compound in general depends upon the size of the cations. The covalent character decreases as size of cation increases LiCl > NaCl > KCl > RbCl > CsCl. Thus LiCl is more covalent than KCl and hence KCl is more soluble in water because of decreased covalent character.
What is the pH of potassium chloride?
The pH value of potassium chloride is 7.
Which of the following has lowest melting point LiCl NaCl KCl RbCl?
Thus, the melting point decreases, but due to the covalent bonding in LiCl (owing to the very small size of Li atom), its melting point is lower than NaCl….Which of the following has the lowest melting point. 1. LiCl. 2. NaCl. 3. KCl. 4. RbCl.
| Compound | Melting Point |
|---|---|
| KCl | 1045 K |
| RbCl | 990 K |
Is KCl neutral basic or acidic?
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.
Which is more soluble LiCl or CsCl?
For solubility hydration enthalpy should be more;Therefore, CsCl is the least soluble of these group 1 chlorides, and LiCl is most soluble.
Which is more covalent And why LiCl or CsCl?
LiCl is more covalent than CsCl since the size of the anion in Lithium chloride is bigger than in Caesium chloride (as per Fajan’s rule). Or interchangeably we can say like the size of cation increases, the covalent characteristic of compounds decreases.
What is the pH of nacl?
≈7
pH of sodium chloride solutions The pH of a sodium chloride solution remains ≈7 due to the extremely weak basicity of the Cl− ion, which is the conjugate base of the strong acid HCl.
Does KCl increase pH?
Adding KCl to the buffer raises its ionic strength, which should be reflected in lowered H+ activity and therefore higher pH.
Which of the following will have highest covalent character and LiCl NaCl KCl RbCl?
Selina – Chemistry – Class 7 RbCl > LiCl > NaCl > KCl is the decreasing order of covalent character. As a result, LiCl has a higher covalent character than KCl, and as a result, KCl is more soluble in water due to its lower covalent character.
Which of the following has higher melting point than RbCl?
NaCl has an interesting property , it’s lattice enthalpy is greater than KCl and RbCl , thus it’s melting point is higher than them. And then comes LiCl who is more ‘Covalent ‘ in nature than NaCl, therefore resulting in a lower melting point than NaCl. This is an indeed interesting thing.
Why is KCl more soluble than NaCl and LiCl?
Due to this regular increase in atomic radius down the group, the bond length will increase. So, among LiCl, NaCl, and KCl, the more soluble will be KCl and least will be LiCl and NaCl will have Solubility more than LiCl and lesser than KCl.
What is the pH of nanacl formed from NaOH and HCl?
NaCl is formed by NaOH and HCl which are strong base and strong acid respectively. So they will completely dissociate and neutralise each other. So the pH will be 7.
Why does the stability of alkali metal chlorides decrease down the group?
Stability of alkali metal chlorides decreases down the group. lattice enthalpy of ionic solid of cation of same valency having same anion decreases. It’s due to down the group size of cation increases so attractive force between anion and cation decreases. Hence Option A iscorrect answer Answer verified by Toppr
Which is more stable CSCL or NaCl?
Difference between Cs and Cl is more so CsCl is unstable. Difference between Na and chlorine is less ,so Nacl is more stable.
