1. Manakah diantara senyawa berikut ini yang termasuk basa Arrhenius….
- A.
MgSO4
- B.
HCl
- C.
Al(OH)3
- D.
CH3COONa
Correct Answer
C. Al(OH)3Explanation
Al(OH)3 is the correct answer because it is a compound that contains hydroxide ions (OH-) which can dissociate in water to release hydroxide ions, making it a base according to the Arrhenius definition of bases. MgSO4, HCl, and CH3COONa do not contain hydroxide ions and therefore do not fit the Arrhenius definition of bases.Rate this question:

1. Bila suatu asam lemah direaksikan dengan basa kuat akan menghasilkan garam yang berisfat …
- A.
Asam
- B.
Basa
- C.
Netral
- D.
Lemah
Correct Answer
B. BasaExplanation
When a weak acid reacts with a strong base, it forms a salt. In this reaction, the weak acid donates a proton (H+) to the strong base, resulting in the formation of a salt and water. Since the strong base completely dissociates in water, it is able to accept the proton from the weak acid and form a new compound called a salt. Therefore, the correct answer is "Basa" (Base).Rate this question:

- C.
Ekstrak kunyit dan BTB
- D.
Indigo carmine dan kertas lakmus
Correct Answer
C. Ekstrak kunyit dan BTBExplanation
The correct answer is "Ekstrak kunyit dan BTB" because both turmeric extract (ekstrak kunyit) and BTB (Bromothymol blue) are examples of natural indicators. Turmeric extract is commonly used as a natural pH indicator, turning from yellow in acidic solutions to red in basic solutions. BTB is a synthetic compound that also changes color depending on the pH of the solution it is in. Therefore, both of these substances can be classified as natural indicators.Rate this question:

Koloid
Correct Answer
B. Garam dan airExplanation
When an acid reacts with a base, it forms a salt and water. This is a common reaction known as neutralization. The acid donates a proton (H+) to the base, forming water, while the remaining ions from the acid and base combine to form a salt. Therefore, the correct answer is "Garam dan air" which translates to "Salt and water" in English.Rate this question:
