Answers
Answer:
The common strong acids are:
hydrochloric acid (HCl)
nitric acid ( HNO3)
hydrobromic acid (HBr)
hope it helps you
Answer:
Acids are very common in some of the foods that we eat. Citrus fruits such as oranges and lemons contain citric acid and ascorbic acid, which is better known as vitamin C. Carbonated sodas contain phosphoric acid. Vinegar contains acetic acid. Your own stomach utilizes hydrochloric acid to digest food. Acids are a distinct class of compounds because of the properties of their aqueous solutions as outlined below:
Aqueous solutions of acids are electrolytes, meaning that they conduct 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 indicates. 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:
Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g)(14.2.1)
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.
It should not be hard for you to name several common acids, but you might find that listing bases is just a little more difficult. Here's a partial list of some common acids, along with some chemical formulas:
Table 14.2.1 : Common Acids and Their Uses
Chemist Name
Common Name Uses
hydrochloric acid, HCl
muriatic acid (used in pools) and stomach acid is HCl) Used in cleaning (refining) metals, in maintenance of swimming pools, and for household cleaning.
sulfuric acid, H2SO4
Used in car batteries, and in the manufacture of fertilizers.
nitric acid, HNO3
Used in the manufacture of fertilizers, explosives and in extraction of gold.
acetic acid, HC2H3O2
vinegar Main ingredient in vinegar.
carbonic acid, H2CO3
responsible for the "fiz" in carbonated drinks As an ingredient in carbonated drinks.
citric acid, C6H8O7
Used in food and dietary supplements. Also added as an acidulant in creams, gels, liquids, and lotions.
acetylsalicylic acid, C6H4(OCOCH3)CO2H
aspirin The active ingredient in aspirin.
In the next section we will begin to examine what, exactly makes an acid an acid, and what makes a base act as a base. Take a look at the formulas given in the first table and take a guess.
Hydrochloric Acid
Hydrochloric acid is a corrosive, strong mineral acid with many industrial uses. A colorless, highly pungent solution of hydrogen chloride (HCl) in water. Hydrochloric acid is usually prepared by treating HCl with water.
HCl(g)+H2O(l)⟶H3O+(aq)+Cl−(aq)(14.2.2)
Hydrochloric acid can therefore be used to prepare chloride salts. Hydrochloric acid is a strong acid, since it is completely dissociated in water. Hydrochloric acid is the preferred acid in titration for determining the amount of bases.
Sulfuric Acid
Sulfuric acid is a highly corrosive strong mineral acid with the molecular formula H2SO4 . Sulfuric acid is a diprotic acid and has a wide range of applications including in domestic acidic drain cleaners,[as an electrolyte in lead-acid batteries and in various cleaning agents. It is also a central substance in the chemical industry.
