The products of any neutralization reaction are water and a salt.
Acid / Base reactions: Produce water and a salt (and sometimes carbon dioxide). Hint: concentrate on the water first. Remember, water has the formula H OH. Complete and balance the following: H Cl + K OH H Cl + Ca( OH ) 2 H OH + KCl 2 Require equal numbers 2 H OH + CaCl 2
1. Ba( OH ) 2 + H 3 PO 4 2. H C 2 H 3 O 2 + Na OH 3. H 2 SO 4 + K OH 4. H 2 CO 3 + Na OH
Remember, strong acids ionize completely in water. The reaction goes all the way to the right. A single arrow is used. There are virtually no HCl molecules left intact.
One more reminder: “Weak” does not mean the same thing as “diluted.” HCl, for example is always a strong acid. If you add 1000 liters of water to it, it will be diluted, but still strong because what little there is will be completely dissociated.
If two wires connected to a light bulb and to a power source are placed in a beaker of water, the light bulb will not glow . If an electrolyte, such as sodium chloride , is dissolved in the water, the light bulb will glow because the solution can now conduct electricity. The amount of electric current that can be carried by an electrolyte solution is proportional to the number of ions dissolved. Thus, the bulb will glow more brightly if the amount of sodium chloride in the solution is increased.
