Examples of Bases and Alkalis
- Sodium hydroxide (NaOH) or caustic soda.
- Calcium hydroxide ( Ca(OH)2 ) or limewater.
- Ammonium hydroxide (NH4OH) or ammonia water.
- Magnesium hydroxide ( Mg(OH)2 ) or milk of magnesia.
- Many bleaches, soaps, toothpastes and cleaning agents.
Simply so, what is an example of a base?
Properties and Examples of Bases. Common examples of bases found at home include soaps; lye, which is found in oven cleaners, for example; milk of magnesia; and Tums. Each has a pH value greater than seven, has the potential for accepting free hydrogen, and can neutralize acids.
What are 5 common bases?
Common Bases and Their Uses
- aluminum hydroxide. color-fast fabrics, antacid, water purification, sticky gel that collects suspended clay and dirt particles on its surface.
- calcium hydroxide. leather-making, mortar and plaster, lessen acidity of soil, called caustic lime.
- magnesium hydroxide.
- sodium hydroxide.
Acids in food such as vinegar (acetic acid), soda water (carbonic acid) and lemon juice (citric acid) are weak acids. Some acids can lose more than one proton. For example, carbonic acid can lose two protons, while citric and phosphoric acids can lose three. Bases, called alkalis if an OH- is involved, accept protons.
Four bases of American dating:
- F1 - French Kissing: First base is equivalent to french kissing, not just kissing.
- F2 - Feeling: Second base is touching of private extremities and/or appendages of the partners' body, aka boob touch.
- F3 - Fellatio: Third base is oral sex.
Uses of bases. Sodium hydroxide is used in manufacture of soap, paper and a synthetic fiber called "rayon". Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder. Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by exhaust, that is found in power plants and factories.
Oranges and lemons, for instance, contain citric acid, which makes them acidic home products.

For example, vinegar in salad dressing is acetic acid, oranges and lemons contain citric acid, and apples contain malic acid. Vitamin C is an acid, ascorbic acid. Bases are also found in common household products. Bases can be very strong and dangerous, or weak and safer for use around the house.
Some common strong Arrhenius bases include:
- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Barium hydroxide (Ba(OH)2)
- Caesium hydroxide (CsOH)
- Strontium hydroxide (Sr(OH)2)
- Calcium hydroxide (Ca(OH)2)
- Lithium hydroxide (LiOH)
- Rubidium hydroxide (RbOH)
If anything a detergent or soap is more of an alkali or base. they are not acidic, although weak acids such as vinegar are sometimes used for cleaning alkaline dirt on glass say. A soap is a base , it is usually made up of sodium hydroxide or potassium hydroxide which are strong alkalis ( or base).
Alkali salts are soluble hydroxides of alkali metals and alkaline earth metals, of which common examples are: Sodium hydroxide – often called "caustic soda" Potassium hydroxide – commonly called "caustic potash" Lye – generic term for either of the previous two or even for a mixture.
They react with metals like zinc to give off hydrogen. Bases in water solutions also show certain properties or characteristics. They taste bitter and and turn litmus paper blue. They also have a slimey or slippery texture to them.
Naming Salts (Ionic Compounds) Salts are ionic compounds which, when dissolved in water, break up completely into ions. They arise by the reaction of acids with bases, and they always contain either a metal cation or a cation derived from ammonium (NH4+). Examples of salts include NaCl, NH4F, MgCO3, and Fe2(HPO4)3.
In chemistry, a weak base is a base that does not ionize fully in an aqueous solution. As Brønsted–Lowry bases are proton acceptors, a weak base may also be defined as a chemical base in which protonation is incomplete. This results in a relatively low pH compared to strong bases.
It is slippery and soapy to the touch after all. The answer would be no. Shampoos are in fact, slightly acidic (around pH 5.5). The common ingredient for achieving this acidity is citric acid, the same acid you find in lemons and oranges.
Thus, sodium hypochlorite is neither an acid or a base. Chlorine bleach is strongly basic. We actually make it by dissolving chlorine gas in a concentrated solution of sodium hydroxide, which forms sodium hypochlorite and sodium chloride, in the following equilibrium.
Some Common Acids and Bases
- Acetic acid (CH3COOH): vinegar, acetate.
- Acetylsalicylic acid (HOOCC6H4OOCCH3): aspirin.
- Ascorbic acid (H2C6H6O6): vitamin C.
- Carbonic acid (H2CO3): soft drinks, seltzer water.
- Citric acid (C6H8O7): citrus fruits, artificial flavorings.
- Hydrochloric acid (HCl): stomach acid.
The neutral substances that are the most well known are: water, table salt, sugar solution and cooking oil. We have learnt about three classes of substances: acids, bases and neutral substances. But, we cannot tell whether a substance is an acid, base, or a neutral substance, just by looking at it.
Many salts are commonly found and used in the home.
- Sodium Chloride. Table salt, or sodium chloride, is the ionic product of the combination of lye, or sodium hydroxide, and hydrochloric acid.
- Ammonium Dichlorate.
- Magnesium Sulfate.
- Sodium Bicarbonate.
Antacids, including sodium bicarbonate (baking soda) and calcium carbonate (Tums), are basic and work by neutralizing stomach acids to water and carbon dioxide (CO2) gas. Bases feel slippery because they are soapy in nature, which is why they are used in cleaners.
Answer 2: In fact, it is quite not accurate to say that hydrogen gains or loses an electron in acid/base. What is more accurate is to DEFINE an acid as a proton donor (the acid gives up a proton) and a base as a proton acceptor (the base takes up a proton).
Water acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide. Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.
In chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.
