3. afua mixes a solution of potassium iodide with a solution of lead nitrate.birth of the solutions are clear and colourless.the resulting mixture is cloudy and yellow.the yellow precipitate is lead iodide,one of the products on this reaction.what is the name of the other products
Jawaban:
Potassium nitrate KNO[tex]_{3}[/tex]
Penjelasan:
2KI + Pb(NO[tex]_{3}[/tex])[tex]_{2}[/tex] ------> 2KNO[tex]_{3}[/tex] + PbI[tex]_{2}[/tex]

4. hasil Kali kelarutan timbal (II)iodide adalah...
Pb2I ---> Pb2+ + I2- ksp = s.s Ksp = s2PbI2 ⇔ Pb2+ + 2I-
s s 2s
Ksp PbI2 = [Pb2+] [I-]²
Ksp PbI2 = [s] [2s]²
Ksp PbI2 = 4s³
Semoga Membantu

6. Which of the following chemicals is a nonelectrolyte?a. molten naphthalenab. sodium hydroxide solutionc. aqueous sulfuric acid solutiond. aqueous ethanoic acid solutione. aqueous potassium iodide solution
The First thing that you must knew about Electrolyte Solution, Have the Criteria:
- The Solution that Perfect Ionized
- Strong Acid or alkali (have strong electrolyte) and weak Acid or alkali (have Weak Elektrolytes)
- Salt Solution (NaCl, KCl, and any others)
I thing Molten Napthalena Is the best Answer, Napthalena as an Organic coumpund has a Stabilized structur, so dificult to ionized.
I Hope that answer your question...

15. When 10 cm³ of 0.5 mol dm3 sodium sulphate solution is added to excess lead (II) nitrate solution, a white precipitate is formed. Calculate the mass of precipitate formed.
Jawaban:
To solve this problem, we need to use the fact that a mole of a substance is a unit of mass equal to the atomic or molecular weight of that substance in grams.
We know that the concentration of the sodium sulphate solution is 0.5 mol/dm³, and that we have added 10 cm³ of the solution. Therefore, the number of moles of sodium sulphate in the solution is 0.5 x (10/1000) = 0.005 moles.
Sodium sulphate has a molecular weight of 142.04 g/mol, so the mass of sodium sulphate in the solution is 0.005 x 142.04 = 0.7102 g.
When sodium sulphate is added to lead (II) nitrate, a white precipitate of lead (II) sulphate is formed. The formula for lead (II) sulphate is PbSO4, and its molecular weight is 303.34 g/mol.
Thus, the mass of lead (II) sulphate precipitate formed is 0.005 x 303.34 = 1.5167 g.
Therefore, the mass of precipitate formed is 1.5167 grams.

19. apa itu potassium nitrat
Pupuk KNO3 ( Potassium Nitrat) merupakan salah satu pupuk kimia yang banyak dicari karena manfaatnya. Kalium dan Nitrogen merupakan nutrisi utama bagi tumbuhan.
20. apa itu Potassium hydroxide (E 525)
kalo satau aku potasium itu sama kayak sianida
sorry kalo salah ^^Kalium hidroksida dapat ditemukan dalam bentuk murni dengan mereaksikan natrium hidroksida dengan kalium murni. Kalium hidroksida biasanya dijual sebagai pelet tembus, yang akan menjadi norak di udara karena KOH adalah higroskopis.
