If I dissolve...

Question

If I dissolve an acid to water it gives me h ions eg. NaCl give Na+cl- ions my teacher said NaCl breaks into h and cl ions what does it mean this compound breaks into na and cl ions how they exist they are already in ionic compound so what does it mean

Open in App

Solution

There will be electro static attraction between Na and Cl in NaCl.So they will remain as such.
But when dissolved in water this electro static attraction is lost and Na and Cl in NaCl will seperate as Na+ and Cl- and contain in water

Q. Assertion :On dissolving

N a C l

in water we get

N a^{+} (a q .)

and

C l^{-} (a q .)

in the solution but

H C l

gives

H_{3} O^{+}

and

C l^{-}

ions. Reason:

N a C l

is ionic and

H C l

is covalent

When NaCl is dissolved in water, it forms $N a^{+}$ and $C l^{-}$ ions. The $N a^{+}$ ions will be attracted by which part of water?

In a book it is written that ions in ionic compounds become free to move in aqueous solution i.e NaCl becomes Na+ and Cl- in aqueous solution and the ions become free to move. Is it true?

Q. What is the distance between
