Suggest a test chemical that can be added to waste water to precipitate lead II ions show a chemical equation for the formation of the precipitate?
Put a little hydrochloric acid in the water sample. 2HCl + Pb -> H2 + PbCl2. Lead chloride is insoluble and its density is much higher than that of water. You can then perform a test on the precipitate to determine the ratio of lead chloride to silver chloride in your precipitate.
How could you detect the presence of the chloride ion?
It Is determined in the flame test. A flame test is when u take the solution and put it on an object non flammable and hold it into the fire and the color of the fire will change. The test is constructed so that depending on the ions in the solution the flame with show whether It has a specific ion based on its distinctive Color.
Why does hydrogen show dual nature?
Hydrogen exhibits dual nature because it can behave both like a metal and a nonmetal. As the first element on the periodic table, it has a simple structure with one electron that can easily lose or gain to form both positive and negative ions. This duality allows hydrogen to display both metallic and nonmetallic properties.
How are hydrogen ion and hydronium ion and hydroxide ion produced?
Water is also unique in that it is both an acid (with H+ ions) and a lye (with OH- ions). It is thus both acidic and basic (alkaline) at the same time, causing it to be strictly neutral as the number of H+ ions equals that of the OH- ions. Because of its strong cohesion, only few water molecules dissociate (split) in their constituent ions: hydrogen ions (H+) and hydroxyl ions (OH-). Chemists would insist that H+ ions are really H3O+ ions or hydronium ions.
What is the ionic equation between halides and silver nitrate?
The ionic equation between halides and silver nitrate involves the cation from silver nitrate combining with the anion from the halide compound to form a precipitate. For example, with chloride ions, Ag^+ from silver nitrate reacts with Cl^- from the chloride compound to form solid silver chloride (AgCl) precipitate. The net ionic equation would show the formation of the silver halide precipitate.
What is the word equation to show the reaction of chlorine and hydrogen?
The elements chlorine and hydrogen react with each another to form the compound hydrogen chloride.
Why does sodium metal and sodium chloride behave different?
Sodium metal is a pure element, while sodium chloride is a compound composed of sodium and chlorine ions. Therefore, their chemical properties and behaviors differ due to the difference in their compositions. Sodium metal is a highly reactive metal, while sodium chloride is a stable compound commonly used as table salt.
How could you show that sea salt contains sodium chloride?
- using a salinometer - by chemical analysis
What state symbol is used to show that sodium chloride is aqueous?
The state symbol used to show that sodium chloride is aqueous is (aq), which stands for aqueous. When sodium chloride is dissolved in water, it dissociates into its constituent ions, sodium (Na+) and chloride (Cl-), and is represented as NaCl(aq).
Industrial preparation of NaOH with diagram?
The industrial preparation of sodium hydroxide (NaOH) is commonly done through the chloralkali process, where a concentrated solution of sodium chloride (brine) is electrolyzed to produce chlorine gas, hydrogen gas, and sodium hydroxide. The diagram would typically show an electrolysis cell with an anode, a cathode, and a brine solution. The anode oxidizes chloride ions to produce chlorine gas, while the cathode reduces water to hydrogen gas and hydroxide ions, which then combine to form sodium hydroxide.

How do you show that propane contains hydrogen?
Propane is a hydrocarbon compound composed of carbon and hydrogen atoms. Its chemical formula is C3H8, indicating that it contains hydrogen atoms. The presence of hydrogen in propane can be confirmed through various analytical techniques such as elemental analysis or spectroscopic analysis.
What happens when HCl is combined with burned Mg?
Magnesium has a valence of 2+. It will react with the Chloride in the HCL. CL has a valence of 1-. So you will need two chloride ions to handle the 1 magnesium ion.Also you have 2 Hydroxide ions (OH) each with a valence of -1You need two Hydrogen ions (H) to balance them as Hydrogen has a valence of 1+So you would need two molecules of HCl per 1 molecule of Magnesium Hydroxide.so.Mg(OH)2 + 2HCl -> MgCl2 + 2H20Answered with help of Yahoo Answers
What is the chemical formula for hydrogen oxide and show your working?
Hydrogen has a valencey of 1 oxygen has a valencey of 2 H1O2 cross nums over H20 another eg Chlorine has valencey of 2 hydrogen 1 CL2H1 CLH2(hydrogen chloride or hydrochloric acid)
Why do HCl and HNO3 show acidic characters in aqueos solutions while solutions of compounds like alcohol and glucose do not show acidic character?
Chlorine, nitrogen, and oxygen are highly electronegative and thus electron withdrawing, which makes it easy for a hydrogen atom to break off in HNO3 or HCl. Glucose, by contrast, contains carbon which is electron releasing, this makes it harder for a hydrogen ion to break off.
What is the correct way to show sodium chloride in aqueous solution?
To show sodium chloride in aqueous solution, you would write it as NaCl(aq), where (aq) denotes that it is dissolved in water. This indicates that sodium chloride has dissociated into its respective ions, Na+ and Cl-, in the aqueous solution.
What is the equation to show that CaCl2 dissociate in water?
The equation to show the dissociation of CaCl2 in water is: CaCl2(s) -> Ca^2+(aq) + 2Cl^-(aq). This equation represents how the solid CaCl2 breaks apart into its ions, calcium ions (Ca^2+) and chloride ions (Cl^-), when dissolved in water.
