acids and bases Flashcards
<p>what is an acid? </p>
<p>substances that dissolve in water to produce hydrogen ions</p>
<p>what is a base?</p>
<p>substances that dissolve in water to produce hydroxide ions</p>
<p>what is a dissociation reaction? </p>
<p>when an acid/base is dissolved in water</p>
<p>acid dissociation reactions: HCl</p>
<p>H+ (aq) + Cl- (aq)</p>
<p>acid dissociation reactions: H2SO4 (aq)</p>
<p>2H+ (aq) SO4-2 (aq) </p>
<p>base dissociation reactions: NaOH (aq)</p>
<p>Na+ (aq) + OH- (aq)</p>
<p>base dissociation reactions: Al(OH)3 (aq)</p>
<p>Al+3 (aq) +3OH- (aq)</p>
do not include water as a reactant since _______
it is known that (aq) means something has been dissolved in water
<p>do we include ionic charges?</p>
<p>yes</p>
<p>acid: taste</p>
<p>sour</p>
<p>acid: touch</p>
<p>n/a</p>
<p>acid: conductivity</p>
<p>good</p>
<p>base: taste</p>
<p>bitter</p>
<p>base: touch</p>
<p>slippery</p>
<p>base: conductivity </p>
<p>good</p>
<p>do acids react with metals?</p>
<p>yes</p>
<p>acids react with metals to form \_\_\_\_</p>
<p>H2 (g)</p>
<p>do bases react with metals?</p>
<p>no</p>
<p>do acids react with carbonates?</p>
<p>yes</p>
<p>acids react with carbonate to form \_\_\_\_, \_\_\_\_ and \_\_\_\_\_</p>
<p>H2O (l) -- water
CO2 (g) -- carbon dioxide
an ionic salt</p>
<p>acid reacting with metal:
| HCl (aq) + Na --> </p>
<p>NaCl + H2 (g)</p>
<p>acid reacting with carbonate:
| 2HCl (aq) + CaCO3 --> </p>
<p>CaCl2 + H2O (l) + CO2 (g)</p>
<p>acids have a \_\_\_ charge</p>
<p>+</p>
