Ch 11 Acids & Bases Test Review
1.Color Change; Universal indicator- yellow, orange and red Blue Litmus paper turns red 2.) Sour taste and conducts electricity 3.) Color change; Universal indicator- dark green, blue, and purple Red Litmus paper turns blue 4.) Bitter taste, slippery feel, and conducts electricity. 5.) pH ) pH ) pH 7 8.) Is the reaction between an acid and base in water that produces salt, water, and a neutral pH 7. 9.) It donates a hydrogen ion creating positive hydronium ion H 3 O +.
10.) It takes a hydronium ion creating negative hydroxide ion OH ) It is neutral because the net charge on the positive hydronium, H 3 O +, and negative hydroxide, OH -, ion are 0 meaning it is neutral or balanced. Also, hydronium and hydroxide bump into each other again to make 2 water compounds that are also neutral. 12.) The indicator gets a hydrogen ion from the hydronium ion, formed from the acid, changing the color to either yellow, orange, or red based on the strength of the acid. 13.) The indicator has a hydrogen ion taken by the hydroxide ion, formed from the base, changing the color to either dark green, blue, or purple based on the strength of the base.
