How is acid and neutralization connected?
Acid is neutralized when it is added to an equal amount of base.
The acid base indicator bromcresol green is weak acid. The yellow acid and blue base forms of the indicator are present in equal concentrations in a sloution when the pH 4.68. What is b.g. pKa?
By definition, the pKa of a weak acid is the pH at which the concentrations of the acid and its conjugate base are equal. In this case, since the solution is yellow (acid) and blue (base) at pH 4.68, it means that the concentration of the acid and base forms of the indicator are equal. Therefore, the pKa of bromcresol green is 4.68.
What is the formula to find moles of a solid acid when they are equal to the liquid base in a neutralization?
moles of acid = moles base = moles base/liter x liters of base used
What type of reaction occurs when equal quantities of acid and base are mixed?
When acid reacts with base, that is a neutralization reaction.
What are the products if equal amounts of an acid and a base react?
When equal amounts of an acid and a base react, they neutralize each other to form water and a salt.
When equal amounts of equal strength acid and base are added together what is formed?
The products are a salt and water.
What is the significance of the equivalence point when titrating a strong acid with a strong base?
The equivalence point in titrating a strong acid with a strong base is significant because it marks the point at which the moles of acid and base are equal, resulting in a neutral solution. This is important for determining the concentration of the acid or base being titrated.
How many times do you have to neutralizer bases using an acid?
The number of moles of acid and the base should be equal to neutralize. (So the number of moles of base is needed to answer this correctly)
Why is DNA acid?
Great question. Deoxyribonucleic Acid is made up of a sugar (the deoxyribose), a phosphate ion, and a nitrogenous base. the phosphate ion is where the acidity is, its also called phosphoric acid while in your cells. You could argue that wouldn't it be equal with base and acidity with the nitrogenous base, but the acid is so much powerful then the base, the base is there just basically for supporting the deoxyribose
Why does the pH change rapidly at the equivalence point of a titration?
The equivalence point represents a region where the amount of acid to base (or base to acid) concentration is equal. Before the equivalence point there is a greater amount of acid (or base, depending on the titration). After the titration there is a greater amount of base (or acid). This reverse in dominance results in a dramatic change in pH.
What two things always form when an acid is neutralized by a base of equal strength?
Water and a salt.
Why doesn't reaction between equal amounts of an acid and a base always produce a neutral solution?
The amount of base needed to neutralize an acid depends on the alkalinity of the acid and of the base. ------------------ Because some salts formed during the neutralization form non-neutral water solutions.
