Bases taste

The world as we know it could not function without acids and bases. These chemical compounds are used extensively, from the chemical laboratory to the manufacturing industry. They are necessary for the proper functioning of the human body and for the health of the environment, too. Acids taste sour, break down metals, and react with bases. Without acids, soft drinks, lemonade, and tomato sauce would not taste the same way. Bases taste bitter, feel slippery, and react with acids. Without bases, cakes would be hard and flat, and laundry detergent would not clean. Both acids and bases can change certain vegetable substances a variety of different colors, and they can burn through human skin if not handled properly. Without acids and bases, we would not have dynamite, some heart medications, and fertilizers. On the other hand, without acids, we would not have damaging acid rain. And... [Pg.1]

Bases have specific properties that mark them as bases, too. Bases taste bitter, but most bases are not food, so they should not be tasted. In fact, no chemical substance should ever be tasted unless you are positive it is safe. Bases also feel slippery to... [Pg.13]

Acids and bases are extremely common substances, as are their reactions with each other. At the macroscopic level, acids taste sour (that is, lemon juice) and react with bases to yield salts. Bases taste bitter (that is, tonic water) and react with acids to form salts. [Pg.53]

As chemists came to understand acids and bases as more than just stuff that burns, their understanding of how to define them evolved as well. It s often said that acids taste sour, while bases taste bitter, but we do not recommend that you go around tasting chemicals in the laboratory to identify them as acids or bases. In the following sections, we explain three much safer methods you can use to tell the difference between the two. [Pg.223]

EthyPharm, disintegrating based, taste Peelable opening... [Pg.672]

BASES taste brackish. They change the color of indicators. They contain a combination of oxygen and hydrogen atoms called "hydroxyl (OH). They neutralize acids. [Pg.43]

DISSOLVE 5 g (1 TEASPOON] LYE IN 50 ml WATER. DROP 5 DROPS OF SOLUTION IN GLASS OF WATER. DIP FINGER IN THIS HIGHLY DILUTED BASE. TASTE DROP ON FINGER TIP. [Pg.43]

Bases taste bitter, feel slippery, and turn red litmus blue. [Pg.127]

The words acid and base are commonly used and can be defined by their properties. The physical properties of these substances are simple. Acids taste sour (consider the taste of a lemon), and they can burn your skin. Bases taste bitter and feel slippery. Soaps and... [Pg.127]

A base tastes alkaline, that is, like lime water it turns red litmus blue, as well as imparting distinctive colors to the other organic substances which may be used in a similar manner it causes a slippery feeling if a drop of its solution is rubbed between the finger tips. These properties of a base are all lost when the base has reacted with an equivalent quantity of an acid. [Pg.108]

One way to distinguish acids from bases is to describe their observable properties. For example, acids taste sour, and they change colour when mixed with coloured dyes called indicators. Bases taste bitter and feel slippery. They also change colour when mixed with indicators. [Pg.370]

As mentioned previously, acids and bases can be defined in a number of ways. One way to define an acid or base is by what you see when an acid or base reacts with other substances. For example, your senses can help you identify an acid or base because acids taste sour and bases taste bitter. The sour taste of lemons can be attributed to the citric acid found in the lemon juice. In addition, bases have a slippery feel to them (please, do not touch or taste acids or bases). [Pg.140]

Acids taste sour or tart bases taste bitter. Bases are slippery when wet. [Pg.94]

Properties of Basic Soiutions Most soaps are bases, so if you think about how soap feels, you can figure out some of the properties of basic solutions. Basic solutions feel slippery. Acids in water solution taste sour, but bases taste bitter— as you know if you have ever accidentally gotten soap in your mouth. [Pg.81]

The taste buds that sense a bitter taste are located at the base of the tongue. Bases taste bitter. Many medications are basic, and pharmaceutical companies spend a lot of time and research trying to mask the bitter taste with other tastes. [Pg.519]

Acids have a sour taste, react with many metals to produce hydrogen gas, turn blue litmus red and neutralize bases. Bases taste bitter, their solutions feel slippery, they turn red litmus blue and they neutralize acids. Both are electrolytes, they ionize in solution. [Pg.406]

In dilute solutions, bases taste bitter. (But you are never going to taste a lab sample, right )... [Pg.196]

The Properties of Bases Tasting Bitter and Feeling Slippery... [Pg.353]

Aqueous solutions of bases taste bitter. You may have noticed this fact if you have ever gotten soap, a basic substance, in your mouth. As with acids, taste should NEVER be used to test a substance to see if it is a base. Many bases are caustic they attack the skin and tissues, causing severe bums. [Pg.445]

During the years of alchemy the chemical compositions of acids and bases were unknown. Alchemists had to rely on the behavior of substances to classify them as acids, bases, or neither. Generally speaking, solutions of acids tasted sour. Solutions of bases tasted bitter and felt sUppery. [Pg.91]
