Acid Base Review Standard 5 Chapter 19

TRUE / FALSE 1.Acids produce OH- ions in water. True False How do you know if it’s an acid or base? HCl  H + + Cl - NaOH  Na + + OH - Mg(OH) 2  Mg 2+ + OH - Bronsted- Lowry acid (Hydrogen ion donator) Bronsted-Lowry base (hydrogen ion acceptor)

TRUE / FALSE 2.Acids and bases usually react to produce water and salt. True False

TRUE / FALSE 3.The neutralization point is reached when equal amount of acid react with an equal amount of base. True False What happens with a strong acid and a weak base = ? Strong base and weak acid = ?

TRUE / FALSE 4.The concentration of reactant and products are the same for strong acids. True False Strong acids dissociate completely!!! Break apart. Therefore no reactant is left. Dissociates = break apart Ionizes = break apart into ions Electrolytes = ions that conduct electricity

TRUE / FALSE 5.Acids accept H + ions in water. True False

MULTIPLE CHOICE 6.Which of the following could be part of a conceptual definition of an acid? I. Acids taste sour II. Acids have high pH III. Acids donate protons a. I and II b. I and III c. III only d. I, II, and III

MULTIPLE CHOICE 7.A concentrated strong acid solution is expected to: a. Ionize completely b. Ionize partially c. Produce OH - ions d. None of the above If these ions are made to conduct electricity then they are called electrolytes (electricity light). Weak acids are called weak electrolytes because they ionize only partially.

MULTIPLE CHOICE 8.Which is true about a basic solution? a. Taste sour b. Has a low pH c. Taste bitter d. None of the above

TRUE OR FALSE 9.Which is true? a. pH of less than 7 is acidic; pH of more than 7 is basic b. pH of less than 7 is basic; pH of more than 7 is acidic c. pH of more than 7 is basic; pH of more than 7 is acidic d. pH of less than 7 is basic; pH of less than 7 is acidic pH scale measure concentration of protons (H + ions) dissociated in solution. The lower the number the higher the concentration

MULTIPLE CHOICE 10.Which of the following is considered a strong acid: a. HCl b. NH 3 c. NaOH d. CH 3 OH Strong vs weak analogy

MULTIPLE CHOICE 11.Which of the following is considered a strong base: a. NaOH b. HI c. NH 3 d. H 2 SO 4

MULTIPLE CHOICE 12.Vinegar, Fruit Juice, and cola are examples of: a. Strong acids b. Weak acids c. Strong bases d. Weak bases

SHORT ANSWERS 13.Complete the following neutralization reaction: KOH + HCl  Label the acid base, and salt. Why is salt always formed?

SHORT ANSWERS 13.Complete the following reaction: HCl + H 2 O  H3O+ is just another way of showing that there are protons/hydrogen ions in the solution.

SHORT ANSWERS 13.Complete the following dissociation reaction in water: NH 4 NO 3  Will it conduct electricity? Salt Describe the dissolving process….
