What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
What are the changes in adding potassium iodide to lead nitrate?
When potassium iodide is added to lead nitrate, a precipitation reaction occurs resulting in the formation of lead iodide, a yellow insoluble solid, and potassium nitrate, which remains in solution. This reaction can be visually identified by the formation of a yellow precipitate.
When you put potassium per magnate into water it changes to what color?
When you put potassium permanganate into water, it changes to a deep purple or violet color.
What happen when chlorine reacts with bromine?
Electrons are shared between the chlorine atoms and the bromine atoms.
What chemical's solubility is most affected by change in temperature potassium nitrate or salt?
Potassium nitrate's solubility is more affected by changes in temperature compared to salt. Generally, the solubility of solids in water increases with temperature. Potassium nitrate has a significant increase in solubility with temperature, while salt's solubility is relatively unaffected by temperature changes.
What colour change is seen when excess potassium iodine is reacted with chlorine?
When excess potassium iodide is reacted with chlorine, the solution changes from colorless to dark brown due to the formation of Iodine (I2). Excess potassium iodide reacts with chlorine to form iodine, which imparts the dark brown color to the solution.
When naming the compound containing potassium and chlorine change the suffi of anions name to?
When naming the compound containing potassium and chlorine, the suffix of the anion's name changes from "-ine" to "-ide". Thus, the compound formed is called potassium chloride.
Why no use indicator in the standardizing potassium permanganate titration?
In the standardization of potassium permanganate titration, an indicator is not used because the titration is self-indicating. This means the solution being titrated changes color at the end point, so an additional indicator is not necessary. It is important to carefully observe the color change to ensure accurate titration results.
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Bromine reacts with an alkane to produce a colorless solution, due to the formation of a colorless alkyl halide. On the other hand, potassium permanganate (KMnO4) reacts with an alkane to form a brown precipitate of manganese dioxide.
What color is the test strip for chlorine sanitizer?
The color of the test strip for chlorine sanitizer typically changes to indicate the level of chlorine present in the solution. It can range from yellow to green to brown, depending on the concentration of chlorine.
What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
Why colour changes to pink when mohr's salt solution is added to potassium permanganate solution?
When Mohr's salt solution is added to potassium permanganate solution, a redox reaction occurs where permanganate is reduced to colorless manganese(II) ions. The pink color observed is due to the remaining manganese(VII) ions from the permanganate that form manganese(VII) ions with Mohr's salt.
Why potassium ferricyanide cannot be used as internal indicator?
Potassium ferricyanide cannot be used as an internal indicator because it is an external indicator that does not change color in response to pH changes in a solution. Internal indicators are usually weak organic acids or bases that change color due to ionization changes as the pH of the solution shifts.
What is the theoretical achromatic point of salivary amylase?
If we add salivary amylase to any solution ( eg:iodine solution) the colour of solution changes to blue.THE TIME TAKEN BY THE SALIVARY AMYLASE TO CHANGE ITS(iodine solution) COLOUR TO BLUE IS CALLED ACROMATIC POINT OF SALIVARY AMYLASE. ie, the time upto which the solution is colourless and after that it gains blue colour.
What are the physical changes in potassium?
Potassium can be melted or boiled.
What are the changes in adding potassium iodide to lead nitrate?
When potassium iodide is added to lead nitrate, a precipitation reaction occurs resulting in the formation of lead iodide, a yellow insoluble solid, and potassium nitrate, which remains in solution. This reaction can be visually identified by the formation of a yellow precipitate.
If potassium was heated and then dissolved in water what would its PH balance be?
The symbol "ph" represents the potential of Hydrogen, measuring how basic or acidic a liquid is. If you add plain, pure Potassium, unless it bonds with Potassium atoms and changes the level of the Hydrogen in solution, I'm not sure it will affect the potential of the Hydrogen.Of course, I took chemistry many years ago. :)
