A voltaic cell is composed with reactants and products in their standard states.So when it operates,the concentration of all substance must change,it should no be hold.Am i right?

Yes, the standard states (also known as standard conditions) refer to a set of defined temperature and pressure conditions that are commonly used in scientific experiments. They are generally considered to be 25 degrees Celsius and 1 atmosphere of pressure. These conditions are still applicable when conducting experiments, regardless of the type of operation being performed.
The standard states can have an impact on experimental results, as they provide a consistent baseline for comparison. By using the same set of conditions, scientists can ensure that their results are comparable with other studies and can be generalized to real-world situations.
Yes, the standard states can be adjusted for different types of operations. For example, in chemical reactions, the standard states may be adjusted to reflect the concentration of reactants or the presence of a catalyst. In thermodynamic experiments, the standard states may be adjusted to account for changes in temperature or pressure.
If the standard states are not followed, it can lead to inaccurate or unreliable results. This is because the conditions under which the experiment is performed can have a significant impact on the outcome. Deviations from the standard states may also make it difficult to compare results with other studies or apply them to real-world scenarios.
Yes, there are exceptions to the standard states. In some cases, different standard conditions may be used depending on the type of experiment being conducted. Additionally, some experiments may require specialized conditions that do not fall under the standard states. It is important for scientists to carefully consider the appropriate standard states for their specific experiment.
