Pablo knows that NaCl dissolves in water and that elements in the same group of the Periodic Table often have similar chemical properties. He develops a hypothesis that states: All chloride salts of group I metals are soluble in water.

He proposes to test his theory by taking a small sample of each type of salt and stirring it into a beaker of water.

What will he observe if his prediction is true?
A.
Each of the solid salts will produce bubbles when mixed with the liquid water.
B.
Each mixture of salt and water will become a different color.
C.
At least some of the solid added will cease to be visible at the bottom of each beaker.
D.
After they are stirred, each of the beakers will each feel hot to the touch.
