Juicing a lemon is a physical change because the lemon's molecules remain the same even though its physical form changes from solid to liquid. The process of juicing just separates the juice from the pulp without altering the chemical composition of the lemon.
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
This color change occurs due to a chemical reaction between the ginger's compounds (anthocyanins) and the acidic lemon juice. The anthocyanins in the ginger react with the acid to change color, resulting in the pinkish hue.
They both create mixtures called solutions.
When lemon juice is mixed with vinegar, it does not change color significantly. Lemon juice is already acidic and adding vinegar, which is also acidic, will not produce a significant color change.
Mixing lemon juice with milk would be a chemical change because the acid in the lemon juice can curdle the proteins in the milk, leading to a change in the chemical composition of the mixture.
Mixing lemon juice and milk would result in a physical change. The two substances retain their original properties and do not create a new chemical compound when mixed together.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
Yes, adding lemon juice to limestone causes a chemical change as the acid in the lemon juice reacts with the calcium carbonate in limestone to form calcium citrate, water, and carbon dioxide.
When soap is mixed with lemon juice, a chemical reaction occurs due to the acidic nature of the lemon juice. This reaction can cause the soap to break down or curdle, leading to a less effective cleaning solution. It is best to avoid mixing soap with acidic substances like lemon juice for cleaning purposes.

When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
This is a chemical change. The hydrogen rich acid from the lemon juice suppresses the slightly negative and highly pigmented ions being produced by certain poly phenol compounds - commonly grouped as tannins. The neutralization of the pigmented ions by the acid in the lemon juice causes the observed lightening of the liquid.
== == Washing Soda+lemon juice=co2+other products == == A chemical reaction has taken place between the reactants, washing soda and lemon juice. Carbon dioxide is one of the products. the chemical change cannot be reversed. So it is a irreversible change.
This color change occurs due to a chemical reaction between the ginger's compounds (anthocyanins) and the acidic lemon juice. The anthocyanins in the ginger react with the acid to change color, resulting in the pinkish hue.
