you'd still end up with a mixture of sodium chloride and potassium iodide because no reaction will occur.
In the iodine clock reaction, sulfuric acid is used as a catalyst to increase the reaction rate. It helps in the oxidation of iodide ions by hydrogen peroxide, which is a key step in the reaction. Sulfuric acid also provides the acidic environment necessary for the reaction to occur.
The elements mix together to create an Iodine Clock Reaction... the last person that answered obviously didn't know what they were talking about and they are bored. i had to answer this for science class and this is the answer you are looking for:)
The chem time clock is a concept in chemistry that refers to the time required for a reaction to reach completion. It is based on the speed of the reaction, which can be influenced by various factors such as temperature, concentration of reactants, and catalysts. The chem time clock helps in predicting when a reaction will finish based on these factors.
The ammonia clock is a chemical clock reaction that changes color over time due to a series of reactions involving the oxidation of iodide ions by ammonium ions in the presence of hydrogen peroxide. The color change occurs because of the alternating formation of different iodine species with distinct colors. The timing of these reactions can be controlled by adjusting the concentrations of the reactants, allowing for the clock-like color change.
Zinc is important for powering a clock because it is commonly used in a zinc-carbon battery, which is a type of dry cell battery. The chemical reaction between the zinc and manganese dioxide in the battery generates electricity to power the clock's movement.
The motivation is to accelerate the reaction.
Iodine ion is not consumed; in the first step the iodine ion is oxidized to iodine, in the second step iodine is reduced to iodine ion.

No, but they are the two best demonstrations of oscillating reactions. The B-Z was discovered first, in the USSR in 1950. It used bromine compounds. The B-R was found in 1972 in San Francisco by two teachers looking for an iodine analogue of the B-Z. See the Wikipedia articles for more info. Warren Rauscher
the iodine does not turn the starch black."The iodine clock reaction is based around the colour change that occurs when iodine reacts with starch, turning from a clear colour to a black-blue colour." (2) The starch allows the iodine and the iodide ions to bond, forming a triodide ion.I2(aq) + I−(aq) ⇌ I3−(aq)In this reaction, iodide is viewed as a base, and iodine is viewed as an acid.The iodine is a ligand and is surrounded by the starch,as for the colour change, that is due to the iodine absorbing all light wavelengths corresponding to colours, hence not letting any through, so what you are seeing when the solution is black, is the absence of light and colour alltogether,hope that helps
1 some reaction can be very fast and consume the products of other reactions as they form, for example multistage reactions like blood clotting. 2 some reactions are highly reversible such as the oscillating clock reactions

Experimental conditions that could be varied in an attempt to affect the rate of the clock reaction include changing the concentration of reactants, temperature of the reaction, presence of a catalyst, pH of the solution, or the ratio of reactants. By altering these factors, the reaction rate can be manipulated and studied to understand the mechanism of the reaction.
A fruit clock gets its power from the chemical energy produced by the fruits it uses as a power source. The fruits undergo a chemical reaction with the electrodes in the clock, generating enough energy to run the clock.
