Dilution is a process in which a solution is made less concentrated by adding more solvent. In this case, the water-soluble solution can be diluted by adding large volumes of water to the spill. Water is commonly used as a diluent because it is readily available, inexpensive, and has a high capacity to dissolve many substances. Adding water to the spill will decrease the concentration of the solution, making it less potent or harmful.

The correct answer is "Be compatible with both the chemical and container." When plugging a hole in a container, it is important for the plug to be compatible with both the chemical being stored in the container and the material of the container itself. This ensures that the plug will effectively seal the hole and prevent any leakage or contamination. Additionally, the plug should also be compatible with plastic if the container is made of plastic material.

Spill control strategies and confinement tactics are implemented to restrict the spread of a product release. The goal is to confine the spill to a limited area, preventing it from spreading further and causing more damage. This approach helps in effectively managing the spill and minimizing its impact on the surrounding environment and population. By confining the spill to a limited area, the cleanup and remediation efforts can be focused and targeted, leading to a more efficient and successful containment of the release.

Absorption refers to the physical process of absorbing or "picking up" a liquid hazardous material. This process involves the solid absorbent surface taking in or soaking up the liquid, effectively trapping it within its structure. It is important to differentiate absorption from the chemical process in which a sorbate interacts with a liquid hazardous material, as absorption specifically refers to the physical process of picking up the liquid.

Vapor dispersion is particularly effective on water-soluble materials because the process involves converting a liquid into a vapor or gas, which allows for the even distribution of the substance in the air. Water-soluble materials can easily dissolve in water and form a vapor, making them well-suited for vapor dispersion. This method is commonly used for applications such as air fresheners or humidifiers, where the water-soluble substances are dispersed in the air to achieve the desired effect.

The correct answer is Overflow dam & Underflow. This is because an overflow dam is designed to allow excess water to flow over the top of the dam when the reservoir is full, preventing flooding. On the other hand, an underflow dam is built to control the flow of water underneath the dam, typically used to divert water for irrigation or hydroelectric power generation. These two types of damming methods serve different purposes and are used in different situations.

Neutralization is a chemical method of containment by which large volumes of water are applied to hazardous materials. This process helps to dilute and neutralize the hazardous substances, reducing their potential harm and preventing them from spreading further. By using water as a neutralizing agent, the hazardous materials can be safely contained and their impact minimized.

Dikes prevent the passage of hazardous material to an area where it will produce more harm. This means that dikes act as barriers to contain and control the hazardous material, preventing it from spreading and causing further damage or harm to the surrounding environment or population.
