According to one acid-base theory, a water molecule acts as an acid when the water molecule:

• accepts an H⁺

• accepts an OH^–

• donates an H⁺

• donates an OH^-

The followIng data were collected by a student performIng an acid-base titration:

Volume of the acid, HCl = 20.0 ml

Molarity of the acid = 0.50 M

Volume of the base, NaOH = 40.0 ml

From the collected data, the concentration of the base should be calculated as:

• 1.0 M

• 2.0 M

• 0.50 M

• 0.25 M

Which compound is insoluble in water?

• potassium bromide

• silver bromide

• calcium bromide

• sodium bromide
