What is a base in general?
A base is a substance that reacts with hydrogen ions and can neutralize the acid. Most bases are minerals which form water and salts by reacting with acids. Bases include the metal oxides, hydroxides, and carbonates.
What is base in chemistry short answer?
In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH−) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue)
What is a base in chemistry kids definition?
A base is a substance that can accept a hydrogen ion (H+) from another substance. A chemical can accept a proton if it has a negative charge, or if the molecule has an electronegative atom like oxygen, nitrogen, or chlorine that is rich in electrons. Like acids, some bases are strong and others are weak.
How do you identify a base?
To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions).

What are some examples of bases in chemistry?
Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) and the water solutions of ammonia or its organic derivatives (amines). Such substances produce hydroxide ions (OH -) in water solutions (see Arrhenius theory).
What is the difference between an acid and a base?
The key difference between acid and base is that acids have pH values ranging from 1 to 7 whereas bases have pH values ranging from 7 to 14. pH value is the minus logarithm of H + ion concentration.
What are some examples of weak bases?
An example of a weak base is ammonia.
What is common use of bases?
A common use of bases is to reduce indigestion. Indigestion is cause by reflux or stomach acid, and the base magnesium hydroxide can be used to neutralise the acid and therefore cure indigestion.
