H+ Ion acceptor.

Question 7

Hydronium Ion

Answer 7

[H+]

Question 8

Hydroxide Ion

Answer 8

[OH-]

Question 9

NEUTRALIZATION REACTION

Answer 9

When an acid and base react in solution to form salt and water.

Question 10

Products of an acid/base reaction

Answer 10

Salt + Water

Question 11

Amphoteric

Answer 11

Acid or Base

Question 12

pH, pOH, [H+], [OH-] Calculation Road Map

Answer 12

Question 13

pH Scale

Answer 13

pH = (-) log [H+]

pOH = - log [OH-]

pH + pOH = 14

[H+] = 2nd Log (-) pH

[OH-] = 2nd Log (-) pOH

[H+] [OH-] = 1E-14

Question 14

If the [H+] =1E-5 in a Coca-Cola what is the concentration of [OH-]? Is the solution acidic, basic, or neutral?

Answer 14

[H+] [OH-] = 1E-14

[OH-] = (1E-14) / ([H+])

[OH-] = (1E-14) / (1E-5)

[OH-] = 1E-9

The solution is acidic because 1E-5 is less than 1E-7.

Question 15

Determine the conjugate acid/base pairs.

NH₃ + H₂O —> NH₄⁺ + OH^-

Answer 15

Question 16

How would you calculate the pH of a solution with a hydronium concentration of 1E-5 M?

Answer 16

pH = -log 1E-5 =5

Question 17

Calculate the pH of a solution with a Hydronium ion concentration of 1.3E-9 M

Answer 17

pH= -log(1.3E-9) =8.89

Question 18

Dilute

Answer 18

relatively small concentration of solute

Question 19

Concentrated

Answer 19

relatively large concentration of solute

Question 20

Concentration

Answer 20

amount of solute per solvent
