Question

Difference between acid and bases

Answer 1

Answer:

Acids and bases are two types of corrosive substances. Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+).

Characteristics of Bases (Alkalis):

• Bitter taste (opposed to sour taste of acids)

• Slimy, or soapy feel on fingers

• Many bases react with acids and precipitate salts.

• Strong bases may react violently with acids. An acid spill can be safely neutralised by using a mild base.

• Bases turn red litmus paper blue

• Bases are substances that contain metal oxides or hydroxides

• Bases which are soluble in water form alkalis (soluble bases)

Bases can be classified into:

• Caustics or alkalis, such as sodium hydroxide (NaOH) and potassium hydroxide (KOH)

• Alkali metals in the metallic form function as strong bases and hydrate to give caustics

• Extremely strong bases (superbases) such as alkoxides, metal amides (e.g. sodium amide) and organometallic bases such as butyllithium

• Some concentrated weak bases, such as ammonia when anhydrous or in a concentrated solution.

Characteristics of Acids:

• taste sour when they are eaten

• can sting the skin when they are touched

• can corrode (or eat away at) metals and skin

• can be used as a reactant during electrolysis due to the presence of mobile ions

• turn blue litmus paper red

• are studied in chemistry and biology

• turn red or orange on universal indicator

Weak Acids

Acids can be classified into:

• Strong acids

• Some concentrated weak acids, for example formic acid and acetic acid

• Strong Lewis acids such as anhydrous aluminum chloride and boron trifluoride

• Lewis acids with specific reactivity, e.g. solutions of zinc chloride

• Extremely strong acids (superacids)

Weak Bases

In chemistry, a weak base is a chemical base that does not ionize fully in an aqueous solution.

A list of weak bases:

NH3 ammonia

CH3NH2 methylamine

C5H5N pyridine

NH4OH ammonium hydroxide

Strong Acids

Strong Bases

Key difference: Acids and bases are two types of corrosive substances. Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+). Ionic compounds are a compound with a positive or negative charge. Bases, on the other hand are ionic compounds that break apart to form a negatively charged hydroxide ion (OH-) in water.

A strong base is a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of a very weak acid in an acid-base reaction.

Here is a list of several strong bases:

Potassium hydroxide (KOH)

Lithium hydroxide (LiOH)

Cesium hydroxide (CsOH)

Sodium hydroxide (NaOH)

It is a bit too deep but hope u understood...
