Base Solution Classification
As with acids, alkaline substances can also be easily found in our daily lives. Its slippery nature and bitter taste are easy ways to recognize alkaline substances. Some examples of alkaline substances that are often used are:
Sodium hydroxide / caustic soda / soda ash and potassium hydroxide, as raw material for cleaning in the household, for example bath soap, washing soap, detergent, bleach and floor cleaner
Magnesium hydroxide and aluminum hydroxide, contained in stomach pain medications (antacids)
Ammonia, for disinfecting solvents (preventing infection) and urea fertilizer raw materials
Just like acids, bases are also divided into strong bases and weak bases. The strength of a base can be determined from its ability to release negatively charged hydroxide ions (OH- ions) when dissolved in water. The more OH ions released, the stronger the basic properties. All basic chemical formulas generally contain the OH– group.
some examples of strong bases and weak bases
As is the case with acid solutions, based on their ability to break down into OH-ions in water, basic solutions can be divided into two types namely, Strong Base Solutions and Weak Base Solutions
Titration of strong acid strong base is a method of determining the level of strong acid solution with a peniter (penitration) of a strong base solution, or determination of the level of a strong base solution with a peniter (penitrating) a solution of strong acid. The end point of the titration is the condition when the color changes of the indicator. The endpoint of the titration is expected to be close to the equivalent point of the titration, ie the condition when the strong acid solution precisely reacts with the strong base solution.
In the titration process of strong acids with strong bases and vice versa, both solutions can be ionized completely. This is because the solution of strong acids and strong bases is included in the strong electrolyte solution which can be ionized completely in water. Thus, the salt created in this reaction has neutral properties.
Therefore, in the titration process of strong acids with strong bases the equivalent point is when the pH of the mixture is equal to 7 (neutral).
Strong base solution
is a base when dissolved in partially or water. all the molecules ionize into OH- ions.
The concept of Salt from strong acids and strong bases
This salt solution is neutral. For example, the neutralization reaction between NaOH and HCl produces a salt of NaCl. In water, fully ionized NaCl produces Na + and Cl- ions
NaOH (aq) + HCl (aq) = NaCl (aq) + H2O (l)
Neutral acid base
Strong strong
NaCl = Na + + Cl-
The Na + ion comes from a strong base and the Cl- ion also comes from a strong acid, so both of these ions are acidic and the Bronsted-Lowry base is weak so that both do not react with water (not hydrolyzed). Therefore the solution is neutral or pH = 7
