What types of ions do bases contain?

Bases have a high concentration of OH- in solutions. Substances like NaOH and KOH are strong bases.


What do acidic substances contain?

All acidic substances contain hydrogen. Not only this, but acidic substances must be able to "donate" a hydrogen ion (proton) to an aqueous solution. In case you needed to know, bases are the same, except instead of hydrogen, they have hydroxide (OH).


Sodium hydroxide strong base?

yes, most substances ending in hydroxide are strong bases


Do bases contain hydroxide ions?

Generally hydroxide ions (in the case of inorganic bases) or nitrogen atoms with a lone pair (in the case of organic bases).


Can you give me examples of base in science?

If, by "base", you mean an alkaline substance, then some examples of bases are the hydroxides (sodium hydroxide, potassium hydroxide, calcium hydroxide, etc.) and ammonia. Bases are often subcategorized as Lewis bases (substances that donate electrons, such as hydroxides) and Bronsted-Lowry bases (substances that accept protons, such as ammonia).


Does a base contain hydroxide ion or produce it in a solution?

Some bases, such as sodium and potassium hydroxides, contain hydroxide ions even in solid form. Others, such as ammonia, produce hydroxide in solution but do not contain any such ions when in pure form.


How are all bases chemically the same?

Because all bases have same characteristics and they reacts the same.


What substances have the highest pH?

Concentrated bases (more than 2M/L) as sodium hydroxide for example.


Is an electrolyte a hydroxide ion?

No. No single ion is an electrolyte because they do not exist on their own as substances. However, some electrolytes, called bases, do release hydroxide ions.


What ion produce in base solution?

All acids contain a hydrogen ion, H+. All bases contain a hydroxide ion, OH-


List of bases?

Bases comprises of hydroxide ions. The examples of bases are as follows: sodium hydroxide magnesium hydroxide calcium hydroxide lithium hydroxide potassium hydroxide


Is KO2 an acid or base?

Potassium Hydroxide (KOH) is a base. Bases contain hydroxide (OH) while acids contain hydrogen (H).
