There are three things you can do to dissolve the salt in water:
1) Stir the solution - you increase the rate at which water molecules will come in contact with the salt crystals
2) Grind the salt - the surface area of the salt will increase thus the contact area between ionic lattice of the crystal that can interact with water, is bigger
3) Increase the temperature - this will increase even more the rate of the solvation by increasing the kinetic energy of the particles
Answer:
Ionic bonds are more powerful than covalant bonds
Explanation:
This is because of their strong lattice structure formed by the attraction between metals and non-merals.
Molecules donot exhibit crystal lattices because of the covslent bonds present in between their molecules
They are on the last level of the atoms
Answer:
Explanation:
pH = - log[H⁺]
8 = - log[H⁺]
[H⁺] = 10⁻⁸
if this concentration of hydrogen ion increases to 100 times
New hydrogen ion concentration
[H⁺] = 10⁻⁸ x 10²
= 10⁻⁶
pH = - log[10⁻⁶]
= 6
new pH will be 6 .
