KUIS TITRASI ASAM BASA

1. Titik dimana asam dan basa habis bereaksi disebut :

Titik ekivalen

Titik akhir titrasi

Titik akhir

Titik titrasi

The correct answer is "titik ekivalen." This is the point in a titration where the acid and base have completely reacted with each other in stoichiometric proportions. At this point, the moles of acid and base are equal, resulting in the complete neutralization of the solution. It is an important point in titration as it indicates that the reaction is complete and that the desired endpoint has been reached.

2. Asam Cuka dititrasi dengan Natrium Hidroksida ini adalah contoh titrasi :

Asam Kuat dengann Basa Kuat

Asam Lemah dengan Basa Kuat

Asam Kuat dengan Basa Lemah

Asam Lemah dengnan Basa Lemah

This question is asking for an example of a titration involving acetic acid (Asam Cuka) and sodium hydroxide (Natrium Hidroksida). The correct answer is "Asam Lemah dengan Basa Kuat" which means weak acid with strong base. This is because acetic acid is a weak acid and sodium hydroxide is a strong base. In this titration, the acetic acid will react with the sodium hydroxide to form water and a salt, in this case sodium acetate. The reaction is as follows: CH3COOH + NaOH -> CH3COONa + H2O.

3. Indikator yang digunakan untuk mentitrasimlarutan H₂SO₄ dengan larutan NaOH adalah :

Metil Merah

Bromtimol Blue

Phenoftalein

Metil Orange

Phenoftalein is used as an indicator to titrate H2SO4 with NaOH because it undergoes a color change from colorless to pink as the solution becomes basic. This makes it easy to determine the endpoint of the titration when all the acid has reacted with the base.

4. Larutan standar Asam / Basa yang kemolarannya diketahui disebut :

Analit

Buret

Titran

Titrasi

The correct answer is "titran." In analytical chemistry, a standard solution of an acid or base with a known molarity is referred to as a titran. This solution is used in titrations, a common laboratory technique used to determine the concentration of an unknown substance by reacting it with a known concentration of a standard solution. The titran is carefully measured and added to the unknown solution until the reaction reaches its equivalence point, allowing for the determination of the unknown concentration.

5. 25 mL larutan Asam Sulfat dititrasi dengan 32 mL larutan Natrium Hidroksida 0,15 M. Tentukan konsentrasi larutan analit Asam Sulfat tersebut :

0,96 mol / L

0,06 mol / L

0,09 mol / L

0,096 mol /L

The concentration of the sulfuric acid solution can be determined using the equation:

M1V1 = M2V2

Where M1 is the concentration of the sulfuric acid solution, V1 is the volume of the sulfuric acid solution, M2 is the concentration of the sodium hydroxide solution, and V2 is the volume of the sodium hydroxide solution.

In this case, M1 = ?, V1 = 25 mL, M2 = 0.15 M, and V2 = 32 mL.

Rearranging the equation, we have:

M1 = (M2 * V2) / V1
= (0.15 M * 32 mL) / 25 mL
= 0.096 mol/L

Therefore, the concentration of the sulfuric acid solution is 0.096 mol/L.
