Does a substance such as coke or pepsi dissolve a piece of chalk quicker depending on its pH levels?
coke is pretty acidic, it is around pH 3.2 and since chalk is a carbonate, it undergoes the a classic acid base reaction similar to the vinegar + baking soda reaction. so it would appear to an observer like it is dissolving faster
but i think if this is a homework question your teacher has asked a flawed question becase the chalk does not dissolve it reacts which is two different things (chemical change vs physical change)
also you have to keep in mind the fact that coke is a pretty saturated solution as it has ~40g of glucose/fructose and this can affect solubility
What else can I help you with?
What colour is spit?
spit is usually a clear or white substance.
Is calcium phosphate soluble?
No, calcium phosphate is insoluble. This is why calcium levels are kept low inside the cytoplasm (eukaryotic cells).
How soon to retest ph after adding borax?
Wait at least 2 hours before retesting the pH after adding borax, as it takes time for the substance to dissolve and mix thoroughly with the water. It's important to allow sufficient time for the chemical reaction to take place and for the pH levels to stabilize before retesting.
Is yellow acid or alkali?
Yellow is not a definitive indicator of whether a substance is an acid or an alkali. The color of a substance is not directly related to its pH or acidity levels. pH testing is required to determine if a substance is acidic or alkaline.
What is the significance of low pH levels in determining the acidity of a substance?
Low pH levels indicate high acidity in a substance. pH measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity. This is significant because acidity can affect chemical reactions, biological processes, and the overall properties of a substance.
Why does apple juice and orange juice evaporate quicker than milk and soda?
cuz its not as dense and actually i believe...depending on the caffeine levels soda evaporates faster
How long does it take for the norforms to dissolve once they are in?
Norforms typically dissolve within a few minutes once inserted into the vaginal canal. The exact time may vary depending on individual factors such as body temperature and moisture levels.
On farmville on Facebook how do you get to higher levels quicker?
Cheat... But i recommend not doing so!
What liquids dissolve?
water because of the split molecules and the oxeygens levels
What colour is spit?
spit is usually a clear or white substance.
How can you get plants for your zen garden in plant vs zombies quick?
Get threw the levels quicker.
What do viscous fibers do?
Viscous fibers dissolve in water to form a gel-like substance in the digestive tract. This gel slows down digestion and the absorption of nutrients, which can help regulate blood sugar levels, lower cholesterol, and promote a feeling of fullness.
What is the function of toxicity?
Toxicity refers to the degree to which a substance can harm living organisms. It can disrupt biological functions, damage cells, and lead to illness or death depending on the type and amount of exposure. Toxicity assessments are important for determining safe levels of exposure to a substance.
How long does it take tophi to dissolve?
The time it takes for tophi to dissolve can vary from a few weeks to several months, depending on factors such as the size of the tophi, the individual's overall health, and the effectiveness of the treatment. Medications like allopurinol or febuxostat are commonly prescribed to help dissolve tophi by lowering uric acid levels in the blood. Consistent treatment and monitoring by a healthcare provider are important for successful resolution.
Latent heat energy levels?
Latent heat is the energy absorbed or released during a phase change without a change in temperature. It is classified into two types: latent heat of fusion, which is the energy involved in changing a substance from solid to liquid or vice versa, and latent heat of vaporization, which is the energy associated with changing a substance from liquid to gas or vice versa. These energy levels vary depending on the substance and the phase change involved.
You can find the pH of a substance by using?
using a pH meter or pH indicator strips, which change color depending on the acidity or alkalinity of the substance. Another method is using universal indicator solution that changes color at different pH levels, allowing you to estimate the pH of the substance based on the color observed.
What does suger dissolve better in?
Sugar has been shown to dissolve better in distilled water than in tap water because of the pH levels. Although, sugar also dissolves in vegetable oil.
