A student is asked to make a solution of sodium hydroxide by dissolving an unknown mass of pellets in 250cm3 of water. 25cm3 of solution is then titrated against a standard solution of hydrochloric acid (0.50M) using a suitable indicator to identify the neutralization point. What are the number of moles of sodium hydroxide in 25.0cm3 and the 250cm3 solution. Volume of sodium hydroxide =25.05cm3, moles of HCl=0.00125 moles

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.

hope this .
