Answer:
cause of the properties of their aqueous solutions. Those properties are outlined below:
Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current. Some acids are strong electrolytes because they ionize completely in water, yielding a great many ions. Other acids are weak electrolytes that exist primarily in a non-ionized form when dissolved in water.
Acids have a sour taste. Lemons, vinegar, and sour candies all contain acids.
Acids change the color of certain acid-base indicators. Two common indicators are litmus and phenolphthalein. Blue litmus turns red in the presence of an acid, while phenolphthalein turns colorless.
Acids react with active metals to yield hydrogen gas. Recall that an activity series is a list of metals in descending order of reactivity. Metals that are above hydrogen in the activity series will replace the hydrogen from an acid in a single-replacement reaction, as shown below:
text{Zn}(s)+text{H}_2text{SO}_4(aq)rightarrow text{ZnSO}_4(aq)+text{H}_2(g)
Acids react with bases to produce a salt compound and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The products of this reaction are an ionic compound, which is labeled as a salt, and water.
[10/31, 6:00 PM] Jana Taher: Bases have properties that mostly contrast with those of acids.
Aqueous solutions of bases are also electrolytes. Bases can be either strong or weak, just as acids can.
Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch.
Bases also change the color of indicators. Litmus turns blue in the presence of a base while phenolphthalein turns pink.
Bases do not react with metals in the way that acids do.
Bases react with acids to produce a salt and water.
Please note that tasting chemicals and touching them are NOT good lab practices and should be avoided in other words, don’t do this at home.
