Example of a weak base?
There are many common examples of weak bases that can be found in daily life. One common example is NH3 or ammonia.
It's not possible to determine whether an acid or base is either strong or weak. The only way is to see it's concentration. To determine whether the liquid is an acid or base is easy. An acid's chemical formula always has Hydrogen ions. Example HNO3 or HCl. Bases always have OH or Hydroxide. Example NaOH2.
An acidic salt is one that will produce an acid pH when dissolved in water. It is a salt formed from a strong acid and a weak base. Example: NH4Cl (ammonium chloride). A basic salt is one that will produce an alkaline pH when dissolved in water. It is a salt formed from a strong base and a weak acid. Example: sodium acetate (CH3COONa).
