Answer 1

Which of the following is true about the equation? (5 points)

True	Ca(OH)2 is the base and CaCl2 is the salt.
False	Ca(OH)2 is the acid and CaCl2 is the salt.

Falso	HCl is the base and Ca(OH)2 is the salt.

Describe the scale used to measure the acidity of a substance. Demonstrate how you could differentiate a weak acid from a strong one. (10 points) The pH scale. pH = -log [H⁺]. A strong acid has a low pH while a weak acid has a higher pH but always < 7

False	Its pH is less than 7.
False	Its pH is greater than 7.
True	It has the same concentration of hydronium and hydroxide ions.
False	It has a greater concentration of hydroxide ion than hydronium ions.
