Interpretation: The substances which are soluble in water needs to be identified.
Concept Introduction: The ability of the solute, to dissolve in solvent is known as solubility. Solubility rules are proposed for different ions, whether they are soluble or not. According to solubility rule, it will be confirm that given salt solution will form precipitate or remain aqueous.
Explanation of Solution
Reason for correct option:
According to the solubility rule, salts that contain Cl-, Br −or I − ions are generally soluble in water. Also, the salts in which elements from group 1 are present, they are soluble in water.
Thus, potassium chloride − KCl is soluble in water as potassium is a group 1 element.
Now, all the salts containing phosphates are insoluble but if cations are Na+, K+ and NH4+, they become soluble. Also, salts in which elements from group 1 are present, they are soluble in water.
Thus, sodium phosphate Na3PO4- is soluble in water.
The ammonium ion slats are generally soluble also, the salts of most sulphates are soluble thus, (NH4)2SO4-is soluble in water.
Salts containing nitrate ion (NO3-) are generally soluble.
Thus, iron (III) nitrate Fe (NO3)3 is soluble
Reason for incorrect option:
Now, salts in which Cl - , Br − and I − ions are present are generally soluble except with the cations Ag+ , Pb2+ and (Hg2)2+ .
Thus, AgCl is insoluble in water.
Carbonates are frequently insoluble. If the cations are from Group II thus, carbonates (are insoluble.
Thus, CaCO3- is insoluble in water
According to the solubility rule, phosphates such as Ca3(PO4)2 and Ag3PO4 are frequently insoluble.
Thus, chromium (III) Phosphate CrPO4- is insoluble
The hydroxide salts are slightly soluble. But, if cations are from group 1, they are highly soluble.
Since, Pb is not a group 1 element thus, Pb(OH)2 is slightly soluble in water.

- Label each of the seven designated regions of the following multi-component, solid-liquid phase diagram for the Zinc - Magnesium system.arrow_forward22arrow_forwardPLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS FOR THE MECHANISM!!! THANKS First image: QUESTION 6. I have to show, with ARROWS and STRUCTURES, the mechanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary. I also tried to draw the mechanism, tell me what to change. Please note that its an AMIDE thats formed not an AMINE the nitrogen has ONE hydrogen and one Phenyl-C-Phenyl. I already asked for this mechanism and got as a final product ...-NH2 not whats shown on the picture, thank you Ths second part. QUESTION 3. I just need a way to synthesize the lactone A, I already started please continue from where I left it Second image: I simply need the products, substrates or reagents, thank youarrow_forward

- A certain inorganic cation has an electrophoretic mobility of 5.27 x 10-4 cm2s-1V-1. The same ion has a diffusion coefficient of 9.5 x 10-6cm2s-1. If this ion is separated from cations by CZE with a 75cm capillary, what is the expected plate count, N, at an applied voltage of 15.0kV? Under these separation conditions, the electroosmotic flow rate was 0.85mm s-1 toward the cathode. If the detector was 50.0cm from the injection end of the capillary, how long would it take in minutes for the analyte cation to reach the detector after the field was applied?arrow_forward2.arrow_forwardPlease solve for the following Electrochemistry that occursarrow_forward
