Mixing universal indicator and corn starch is primarily a physical change rather than a chemical change. The universal indicator will change color based on the pH of the solution, while corn starch remains unchanged in composition. However, if the mixture is heated or undergoes a reaction that alters the starch, then a chemical change could occur, but simply mixing them does not constitute a chemical change.
Yes, corn is a noun; a singular or mass, common, concrete noun. The noun corn as a blemish on the foot can be singular or plural; 'a corn' or 'two corns'. The noun corn as the vegetable is a mass noun; 'a field of corn', 'an ear of corn', 'a bowl of corn', or 'a kernel of corn'.
The pH of tomato ketchup is 3.85
We can use a pH paper.

Corn is considered to be slightly acidic, with a pH level ranging from 5.2 to 6.9.

Corn typically grows best in slightly acidic to neutral soil with a pH range of 6.0 to 7.0. If soil pH is too low (acidic) or too high (alkaline), it can affect nutrient availability for the plant and hinder growth. It's important to maintain the proper pH levels for optimal corn growth.
HFCS (high fructose corn syrup) should have no effect on pH, The amount of dissolved carbon dioxide, phosphoric acid, citric acid and others can lower the pH to as low as 2.5
actually, corn oil doesn't release hydrogen or hydroxide ions in water because it doesn't even mix with water. However, i recently conducted an experiment to find the pH of corn oil using special litmus paper and found it to to be 6. Hope this helps!
A good, fertile, tilthy silt loam with a pH around 6.5.
Corn, or maize, can be grown nearly anywhere that the soil is relateively neutral (pH 5.5 to 8.0), sufficient moisture can be delivered to the plant, and sufficient plant nutrients can be held in the soil. Corn will grow in a wide variety of climates.
Very few foods are basic. Winter melon juice, with a pH of 7.2, is the most alkaline vegetable juice. Depending on the variety, corn juice may have a similar pH.
Corn needs well-drained soil that is fertile and rich in nutrients to grow properly. Typically, corn plants grow best in soil with a pH level between 6.0 and 6.8. It is recommended to provide at least 18 inches of soil for corn to develop a strong root system.
The leaves of your corn plant may be turning yellow due to a lack of nutrients, such as nitrogen, or inadequate sunlight. It could also be a sign of overwatering or a soil pH imbalance.
Light green leaves on a corn plant can be a sign of nutrient deficiency, particularly nitrogen. Check the soil pH and consider adding a balanced fertilizer to address the issue.
