What is the volume of a 0.0355mol/l calcium hydroxide solution required to react completely with 50.0ml of 0.250mol/l aluminum sulfate solution

V₁ =  0.35 L

Explanation:

Given data:

Molarity of calcium hydroxide = 0.0355 M

Volume of aluminium sulfate = 50.0 mL ( 50/1000 = 0.05 L)

Molarity of aluminium sulfate = 0.250 M

Volume of calcium hydroxide = ?

Solution:

M₁V₁ = M₂V₂

V₁ = M₂V₂ / M₁

V₁ =  0.250 M .  0.05 L / 0.0355 M

V₁ =  0.0125 M.L/ 0.0355 M

V₁ =  0.35 L

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
