i think it starts to turn different colors or fizzes ;) hope im right cuz im writing it for my homework
Hydrogen gas does not directly react with limewater (calcium hydroxide solution) to produce a visible change. Limewater is typically used to test for the presence of carbon dioxide, which would cause the solution to turn milky due to the formation of insoluble calcium carbonate.
The chemical equation for the reaction between sodium hydrogen carbonate (NaHCO3) and limewater (Ca(OH)2) is: NaHCO3 + Ca(OH)2 → CaCO3 + NaOH + H2O This reaction produces calcium carbonate (CaCO3), sodium hydroxide (NaOH), and water (H2O).
When copper is mixed with limewater, no immediate reaction occurs. Limewater is a solution of calcium hydroxide, which is not reactive with copper. However, if copper is exposed to air and moisture over time, it may develop a greenish layer of copper carbonate on its surface.
Bubbles form when carbon dioxide gas dissolves in the limewater solution, creating a chemical reaction that forms calcium carbonate. The formation of calcium carbonate is visible as the bubbles of carbon dioxide gas are released, giving the appearance of bubbles forming in the solution.
The limewater test can differentiate between carbon dioxide and nitrogen. When carbon dioxide is bubbled through limewater, it turns milky due to the formation of calcium carbonate. Nitrogen will not have this effect on limewater.

The limewater would likely disrupt the pH balance inside the bacterial cells, affecting their ability to function properly. This could lead to cell damage or death depending on the concentration of limewater and the type of bacteria present in the dish.
the positive test for oxygen is very simple. all that needs to happen is a vile must be filled 1/4 with hydrogen peroxide and a glowing splint must be inserted in t the vile . the splint will reignite after it is inserted int the vile.

to test for carbon dioxide is already dissolved in limewater , after this shake up the test tube , is it be that carbondioxide is present then two things will happen : 1) the limewater will turn cloudy as co2 is a precipatate is this solution 2)the limewater will begin to show efferevescence now we know gas is present if these two thing happen then there is an extremly high chance that co2 is present.
limewater.
Oxygen does not have a direct effect on limewater. Limewater is a solution of calcium hydroxide, and when exposed to carbon dioxide, it forms calcium carbonate, turning the limewater milky. Oxygen does not directly interact with the limewater in this chemical reaction.
Limewater fizzes when blown into through a straw.
When you mix hydrochloric acid (HCl) with magnesium (Mg), a chemical reaction will occur, producing hydrogen gas and magnesium chloride. The reaction can be written as: 2HCl + Mg -> MgCl2 + H2. This reaction will also release heat.
A limewater with a pH of 10.5 is considered basic or alkaline. It indicates that the solution has a high concentration of hydroxide ions (OH-) compared to hydrogen ions (H+). This makes it suitable for various applications, such as neutralizing acids or precipitating certain metal ions.
