If 18.7 ml of 0.01500 maqueous hcl is required to titrate 15.00 ml of an aqueous solution of naoh to
the equivalence point, what is the molarity of the naoh solution?

The molarity of  NaOH is 0.02 M.

Explanation:

Given data:

Volume of HCl = 18.7 mL

Molarity of HCl = 0.01500 M

Volume of NaOH = 15.00 mL

Molarity of NaOH = ?

Solution:

M₁V₁  = M₂V₂

0.01500 M × 18.7 mL  = M₂ ×  15.00 mL

M₂ = 0.3 M.mL /15.00 mL

M₂ = 0.02 M

The molarity of  NaOH is 0.02 M.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
