An acid is defined as a proton (Hydrogen ion) donor. An acid has a high concentration of Hydrogen ions. For example Hydrochloric Acid (HCl) is a strong acid which dissociates as below:
HCl --> H+ + Cl-
A base is defined as a proton (Hydrogen ion) acceptor, as it has a high concentration of hydroxide (OH-) ions. These OH- ions can then react with H+ ions in a solution to form water, thus removing hydrogen ions from the solution and causing it to become more basic.
In a neutralisation reaction between an alkali such as NaOH and an acid such as HCl :
NaOH + HCl --> NaCl + H2O
The ionic equation is:
OH- + H+ --> H2O
The base, NaOH has accepted a proton from HCl, whilst the acid, HCl has donated a proton to the NaOH. Water is formed, and the remaining ions Na+ and Cl- form an aqueous solution of NaCl.

∙ 15y agoAcids have a higher concentration of the hydronium ion than the hydroxide ion. Bases have a higher concentration of the hydroxide ion than the hydronium ion. This is a consequence of the definition of pH. pH is equal to the -log([H3O+]), so as the concentration of the hydronium ion increases, the pH decreases. Lower pH = more acidic.

∙ 11y agowhen concentration of H+ ions is more (or OH- ions is less), then it is more acidic.
when concentration of OH- ions is more (or H+ ions is less), then it is more basic.

Is sodium hydroxide a bases or acids?
base
Do all bases end with hydroxide?
ammonia. it's a weak base that accepts a hydrogen for water forming a hydroxide and ammonium
Does aluminium react with acid?
Aluminium is amphoteric which means that it displays some of the properties of both acids and bases, it will react with some bases, such as Sodium Hydroxide and also with some Acids such as concentrated Nitric Acid
Why is sodium hydroxide a base?
Because the conjugate acid of a strong base is a much weaker acid than water. Since the conjugate acid is so weak, its chemical action as an acid is negligible in solution. Strong bases have very weak conjugate acids. Weak bases have relatively strong conjugate acids. The same is true for the conjugate bases of strong acids, such as HCl. Cl- is a much weaker base than than water, so its effects are also negligible.
What are the major groups of inorganic compounds?
INORGANIC COMPOUNDS water-is the most abundant molecule in all organisms. -it also posses unique properties that make it highly essential in biological systems.. PROPERTIES OF WATER # ability to dissolve substances. water is a universal solvent. it can dissolve almost anything. # HYDROGEN-bonding ability. water molecules have an extensive network of hydrogen bonds. this network results in high heat capacity, high heat of evaporation, and high heat of fusion of water. acids-comes from the Latin word acidus meaning 'sour'. -may be classified as strong and weak. PROPERTIES IF ACIDS # they have a sour taste. # they turn blue litmus paper into red. # they react w/ active metals to form hydrogen gas. bases-have poperties that contrast thse of acids. bases are substances that yield hydroxide ions (OH-) in a water solution, while acids are substances that release hydrogen ions(H+). PROPERTIES OF BASES # they taste bitter and feel slippery. # they turn red litmus paper to blue. # like acids, they are also corrosive to the skin. salts
When dissolved in water acids release and bases release .?
acids release hydrogen ions bases release hydroxide ions
Do acids release hydrogen ions?
yes they do and bases release hydroxide ions
What ion is given off by acids?
Hydrogen ions are present in acids, hydroxide ions are present in bases.
When dissolved in water acids release and bases release?
acids release hydrogen ions bases release hydroxide ions
How do acids differ from basis?
Acids have a pH level below 7 while bases have a pH above 7. The chemical difference between acids and bases in the hydrogen ion concentration[H+]. Acids have a higher concentration of hydrogen ions while bases have a higher hydroxide ion concentration[OH-]
How do you tell acids and bases apart according to Arrhenius?
Acids were compounds with hydrogen that ionized when aqueous to form H+. Bases were compounds that ionized when aqueous to form OH- (hydroxide).
What are acid and base?
Acids, bases and salts are chemical compounds. Examples are: Acids: sulfuric acid, nitric acid, stearic acid, phosphoric acid, hydrofluoric acid etc. Bases: sodium hydroxide, magnesium hydroxide, calcium hydroxide, lithium hydroxide etc. Salts: sodium chloride, gallium arsenide, potassium bromide, uranyl nitrate etc.
In a water solution how do acids differ from bases?
Acids form hydrogen ions (H+), while bases form hydroxide ions (OH-).
Can a base be neutralized by a hydroxide if not why?
Hydroxide compounds such as sodium hydroxide (NaOH) are bases. Bases do not neutralize other bases. Acids neutralize bases.
What kinds of ions do acids and bases form in water?
What kind of ions does a base release in a water solution?
A substance that accepts a proton?
In terms of chemistry, a proton is an ionized hydrogen atom, H+. These are released by acids, and they are bound by the hydroxide ion, OH- which in combination with the hydrogen ion turns into a water molecule, H2O. Hydroxide ions are released by a base such as NaOH. The reaction between hydrogen ions and hydroxide ions is the neutralization reaction between acids and bases.
Why is a base the name of the substance that forms hydrogen ions in water?
ACIDS form hydrogen ions H+ in water. Bases form hydroxide ions OH-in water
