2. Dalam suatu pelaksanaan praktikum, siswa diberi larutan berupa HCL dan KOH untuk meneliti gejala apa yang terjadi pada kedua larutan tersebut dengan rangkaian alat seperti gambar disamping. gejala yang terjadi sebagai berikut : a. ada gelembung b. tidak ada gelembung c. lampu menyala d. lampu tidak menyala .

a dan c

a dan d

b dan c

b dan d

The correct answer is "a dan c" because the presence of bubbles (gelembung) indicates a chemical reaction between the HCl and KOH solutions, producing a gas. The lit lamp (lampu menyala) indicates that there is an electric current flowing through the circuit, which is a result of the reaction between the two solutions.

2 dan 4

3 dan 4

1, 2, dan 3

The correct answer is 1, 2, and 3. This is because the presence of gas bubbles on the electrode (gejala 1) indicates a chemical reaction occurring, which is a characteristic of a conducting solution. The bright light (gejala 2) indicates the presence of a strong electrical current passing through the solution. The dim light (gejala 3) suggests a weaker electrical current, but still indicates conductivity. Therefore, all three symptoms demonstrate the ability of the solution to conduct electricity.

4. Terdapat tiga macam air dari sumber yang berbeda, yaitu air laut, air sungai, dan air hujan. Setelah dilakukan pengujian dengan alat penguji elektrolit, ternyata semua air tersebut dapat menyalakan lampu. Pernyataan yang benar dari peristiwa tersebut adalah ....
.

semua air tidak mengandung zat terlarut dan bukan elektrolit

semua air merupakan elektrolit, tetapi tidak mengandung zat terlarut

semua air mengalami ionisasi, tetapi bukan merupakan elektrolit

semua air merupakan elektrolit dan tidak mengalami ionisasi

partikel-partikel zat terlarut mengalami ionisasi da merupakan elektrolit

The correct answer is "partikel-partikel zat terlarut mengalami ionisasi da merupakan elektrolit." This is because the question states that all three types of water (air laut, air sungai, dan air hujan) can light up a lamp when tested with an electrolyte tester. This indicates that the water contains dissolved substances that can conduct electricity, making it an electrolyte. The answer choice correctly states that the dissolved particles undergo ionization and are electrolytes.

5. Jika suatu senyawa elektrolit dilarutkan ke dalam air, maka air akan _____ menjadi ion positif dan negatif.

When a compound is dissolved in water, it undergoes a process called ionization. This means that the compound breaks apart into ions, which are charged particles. In this case, the compound is an electrolyte, which means it can conduct electricity when dissolved in water. When it undergoes ionization, the compound will dissociate into positive ions (cations) and negative ions (anions). Therefore, the correct answer is "terionisasi" which means ionization in English.

6. apakah larutan non elektrolit merupakan larutan yang yang terionisasi true or false?

True

False

A non-electrolyte solution is a solution that does not conduct electricity. This is because non-electrolytes do not dissociate into ions when dissolved in water. In contrast, electrolytes are substances that dissociate into ions in water and can conduct electricity. Therefore, the statement "larutan non elektrolit merupakan larutan yang terionisasi" is false, as non-electrolyte solutions do not undergo ionization.

7. dari beberapa larutan berikut, yang merupakan larutan elektrolit kuat adalah..

NaCL

Mg(OH)2

HCL

CH3COOH

NaCl and HCl are strong electrolytes because they completely dissociate into ions when dissolved in water. NaCl dissociates into Na+ and Cl- ions, while HCl dissociates into H+ and Cl- ions. This means that they conduct electricity well in solution. On the other hand, Mg(OH)2 and CH3COOH are weak electrolytes because they only partially dissociate into ions in water. Mg(OH)2 dissociates into Mg2+ and OH- ions, while CH3COOH dissociates into CH3COO- and H+ ions. Therefore, NaCl and HCl are the only strong electrolytes among the given options.

3, 4, dan 5

The correct answer is 1, 2, dan 3. The substances listed in options 1, 2, and 3 (urea, cukai, and garam) are all capable of conducting electricity when dissolved in water. This is because they dissociate into ions, which are charged particles that can carry an electric current. Therefore, these substances can conduct electricity in solution.

9. Dengan menguji elektrolit elektrode dimasukkan ke dalam larutan asam klorida. Ternyata lampu menyala. Hal ini disebabkan ....

asam klorida memperbesar konsentrasi ion H+ sebagai syarat penghantar listrik

asam klorida dalam keadaan murni tersusun dari ionion

pelarutan asam klorida dalam air terjadi pengeluaran elektron

asam klorida terionisasi sebelum elektrode dihubungkan dengan baterai

asam klorida terionisasi karena adanya arus listrik

The correct answer is "asam klorida terionisasi sebelum elektrode dihubungkan dengan baterai." This means that the hydrochloric acid dissociates into ions before the electrodes are connected to the battery. This is the reason why the lamp lights up when the electrolyte is inserted into the hydrochloric acid solution.
