Will the color change if copper metal is added to silver nitrate solution change?
Yes, a color change will occur. When copper metal is added to silver nitrate solution, a displacement reaction takes place where copper replaces silver in the solution. This leads to the formation of copper nitrate and silver metal, resulting in a change in color from clear to blue as silver particles are formed.
Why does the color of AGCL change?
The color of silver chloride (AgCl) can change due to various factors such as exposure to light, impurities present, or changes in temperature. When AgCl is exposed to light, a photochemical reaction can occur, leading to a change in color from white to gray or pale yellow. Other impurities or reactions can also lead to color changes in silver chloride.
Why do some substances require larger additions before a color change was seen?
Substances may require larger additions before a color change is seen because the color change is based on a chemical reaction that needs a certain amount of the added substance to reach a threshold concentration for the observable change to occur. In some cases, the reaction may be slow or the color change may not be very pronounced until enough of the reacting substances have combined.
When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
List four clues that a chemical reaction is occurring?
To tell if a chemical reaction has occurred look for these four things: 1) color change 2) the formation of gas bubbles 3) formation of a precipitate 4) temperature change
What events occur in light reactions?
change of color(: ?
Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
What color does pH paper turn in neutral solutions?
No change occur.
Do dogs change color as they age, and if so, what are the typical color changes that occur?
Yes, dogs can change color as they age. Some common color changes that occur in dogs as they get older include graying of the fur, darkening or lightening of coat colors, and development of spots or patches.
Will cactus change color if you dye the water?
Plants absorb water for hydration and nutrient intake, but the dye particles are unlikely to be absorbed by the cactus to affect its color. The color change in the cactus would not occur simply by dyeing the water it absorbs.
What color does mixture turn when HCl is mixed with Sodium Chloride?
Any change occur.
Why is the inner-border of my iris getting a bit brighter every month or so?
Eye color can change with age. Slight color changes can occur from disease or a change in hormones.
When paper changes from yellow to brown in sunlight what type of change occurred?
A chemical change. Color change is a good indicator of a chemical change.
What are the two main kinds of changes that can occur when chemical reactions occur?
color change. thats the one i know but i dont know the other one unless its gas formation
What conditions does physical change occur in materials?
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
Will the color change if copper metal is added to silver nitrate solution change?
Yes, a color change will occur. When copper metal is added to silver nitrate solution, a displacement reaction takes place where copper replaces silver in the solution. This leads to the formation of copper nitrate and silver metal, resulting in a change in color from clear to blue as silver particles are formed.
Is a lobster turning red while cooking a chemical change?
Yes, the change in color of a lobster while cooking is a chemical change. This occurs due to a process called denaturation, where the proteins in the lobster's cells change and the pigments responsible for its red color become more prominent.
