A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid.
A chemical change is when the reaction forms a new substance. eg gas bubbles.
An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
The ability to neutralize an acid is a chemical property, as it involves a reaction between the acid and the neutralizing agent to form new substances with different properties.
The solubility of iron in hydrochloric acid is a chemical property, not a physical property. This reaction involves a chemical change where iron reacts with hydrochloric acid to form iron chloride and hydrogen gas is evolved.
The lack of reaction between copper metal and acid is a chemical property because it indicates the chemical stability of copper in acidic environments. This property is due to the formation of a protective layer of copper oxide on the metal surface.
Chemical property because acid is a chemical
Reacting with acid to form H2 is a chemical property, as it involves a change in the chemical composition of the substance. Physical properties, on the other hand, pertain to characteristics like color, density, and state of matter.
chemical reaction
Chemical property: Reacts with acid to form a salt and water through a neutralization reaction. Physical property: Acid-base indicators change color in the presence of an acid.
The ability to neutralize an acid is a chemical property, as it involves a reaction between the acid and the neutralizing agent to form new substances with different properties.
The ability to neutralize stomach acid is a chemical property, as it involves a chemical reaction between an acidic substance and a base to achieve a neutral pH. It is not an inherent physical characteristic of the substance itself.
Sulphurous acid is not a reaction (chemical or physical); the sulphurous acid (H2SO3) is a chemical compound.
Chemical property because acid is a chemical
This is a chemical reaction.
The corrosive action of acid rain on granite is a chemical property. It involves a chemical reaction between the acid in the rain and the minerals in the granite, leading to its deterioration over time. This reaction changes the chemical composition of the granite, making it a chemical property.
The solubility of iron in hydrochloric acid is a chemical property, not a physical property. This reaction involves a chemical change where iron reacts with hydrochloric acid to form iron chloride and hydrogen gas is evolved.
The lack of reaction between copper metal and acid is a chemical property because it indicates the chemical stability of copper in acidic environments. This property is due to the formation of a protective layer of copper oxide on the metal surface.
The reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) is a chemical reaction (property). CH3COOH + NaHCO3 ==> CH3COONa + CO2(g) + H2O
This is a chemical reaction (dito change).
