Interpretation:
The solubility of the given Potassium monohydrogen phosphate in water has to be identified. The ions present in the aqueous solution of potassium monohydrogen phosphate has to be identified.
Concept introduction:
Most of the ionic compounds are soluble in water, very few of the ionic compounds are sparingly soluble, and some of the ionic compounds are insoluble in water. When it is soluble in water ions gets separated in the solution.
Soluble compounds in water:
All
Almost all the salts of
Most of the sulfates are soluble except
All the chlorate
Salts of F- are soluble. But some of the fluoride salt of
Salts of
Insoluble compounds in water:
All phosphates
All chromates
All hydroxides are insoluble except
All oxalates
All sulfides
Most of the metal hydroxides and oxides are insoluble in water bit some of the alkali metal hydroxides,
Dissociation:
When ionic compound dissolved in water it produced cation and anion, this process is called as dissociation.
Generally the ionic compound consists of cation and anion.
Cation: When electrons are removed from the atom that results to form positively charged ion called cation.
Anion: Addition of electron to atom results to form negatively charged ion called anion.

- The US Environmental Protection Agency (EPA) places limits on the quantities of toxic substances that may be discharged into the sewer system. Limits have been established for a variety of substances, including hexavalent chromium, which is limited to 0.50 mg/L. If an industry is discharging hexavalent chromium as potassium dichromate (K2Cr2O7), what is the maximum permissible molarity of that substance?arrow_forwardWhich symbols are used to indicate solids, liquids, gases, and aqueous solutions in chemical equations?arrow_forwardWhat is the difference between a solute and a solvent?arrow_forward

- ssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.arrow_forwardWrite a chemical equation representing the decomposition of water into two gaseous products. What are the products?arrow_forwardMany over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward
