This is the preparation of Insoluble Salts.Insoluble Salts can be made by precipitation. This involves mixing a solution that contains its Positive ions with another solution that contains its Negative ions, For example , insoluble silver chloride is precipitated when solutions of silver nitrate and sodium chloride solutions are mixed together.
What else can I help you with?
What does it mean if you are to carry out an investigation to determine the formula unit of an ionic compound by the use of a precipitation reaction between aqueous solutions?
For reference - here are some definitions: * formula unit of an ionic compound - the lowest whole number ratio of the ions in an ionic compound (shows the ratio of the kinds and numbers of atoms in the compound - e.g. NaCl for sodium chloride) * precipitation reaction - reaction with two aqueous solutions that forms a solid Attempts to reword question: --> Use precipitation reaction between aqueous solutions to work out the formula unit of the ionic compound. How to do this? Will expand when I work it out.
What types of chemical reactions fit with the following statement 'Has only Ionic compounds as reactants and products'?
One type of chemical reaction that fits this statement is a precipitation reaction, where two ionic compounds react to form a precipitate, which is also an ionic compound. Another type is a neutralization reaction, where an acid (ionic compound) reacts with a base (another ionic compound) to form water and a salt, which is an ionic compound.
Ph may affect the solubility of ionic compounds?
Yes, pH can affect the solubility of ionic compounds by influencing the charge on the ions. For example, changing the pH can alter the solubility of metal hydroxides by affecting the balance between the ions and their solid form. This can result in precipitation or dissolution of the ionic compound.
What is the process by which ions leave a solution and regenerate an ionic solid?
The process by which ions leave a solution and regenerate an ionic solid is called precipitation. It occurs when the concentration of ions in a solution exceeds the solubility limit, causing the excess ions to come together and form a solid precipitate. This can be achieved by adding a precipitating agent or by changing the conditions, such as temperature or pH, to reduce the solubility of the ions.
When the ionic compound KI is dissolved in water?
When the ionic compound KI (potassium iodide) is dissolved in water, it dissociates into its constituent ions: K+ and I-. The solution will conduct electricity due to the presence of mobile ions and will likely exhibit properties such as color changes or precipitation reactions, depending on the specific reaction involved.
What is the function of ssc buffer?
SSC buffer increases ionic strength so precipitation of DNA or RNA is increases.CHARUSAT UNIVERSITY.
How does NaCl react with ionic compounds?
An example is the precipitation reaction with silver nitrate: NaCl + AgNO3 = NaNO3 + AgCl(s)

Can a soluble substance become in soluble?
If there is no reaction occuring to change the molecular structure of the substance, you have to look at the ionic product of the substance. When the ionic product is more than the Ksp of the substance, there would be precipitation of the substance
What is precipitation titration's principle?
Precipitation titration is a method of quantitative analysis where a precipitate is formed when a specific reaction occurs between the analyte and titrant. The endpoint is reached when the formation of the precipitate is complete. The amount of analyte is determined by measuring the volume or mass of the titrant required to reach the endpoint.
How do you determine which one of the products in a precipitation reaction is the precipitate?
In a precipitation reaction, the product that is insoluble in water is the precipitate. This can be determined by looking at solubility rules for common ionic compounds or by conducting a simple solubility test to see which substance forms a solid when two solutions are mixed.
What is the net ionic equation of sodium acetate and barium hydroxide?
The net ionic equation for the reaction between sodium acetate (NaCH₃COO) and barium hydroxide (Ba(OH)₂) is: CH₃COO⁻(aq) + Ba²⁺(aq) → Ba(CH₃COO)₂(s) Sodium ions and hydroxide ions do not participate in the formation of the precipitation of barium acetate, so they are not included in the net ionic equation.
Why is it difficult to use precipitation technique for separation of trace elements?
The precipitation technique for separating trace elements is challenging due to the low concentrations of these elements, making it difficult to achieve effective and complete precipitation. Additionally, trace elements often have similar chemical properties, which can lead to co-precipitation with other compounds, resulting in contamination or loss of the target element. Furthermore, the solubility of the precipitate can vary significantly with changes in pH and ionic strength, complicating the separation process.
