To make sure we stay safe in this virtual lab; what should we do to reduce risk when working with high concentration acids? a) Work in large volumes b) Increase their concentration c) Dilute them d) Neutralise them

The correct answer is c) Dilute them.<br /><br />When working with high concentration acids, it is important to reduce the risk of accidents or injuries by diluting them. Dilution involves adding a solvent, usually water, to the acid to decrease its concentration. This makes the acid less corrosive and less likely to cause harm.<br /><br />Working in large volumes (option a) is not a safe practice because it increases the amount of acid present, which can lead to accidents or spills. Increasing the concentration of the acid (option b) is also not safe because it makes the acid more corrosive and dangerous. Neutralizing the acid (option d) is not always necessary and can be time-consuming.<br /><br />Therefore, the best way to reduce risk when working with high concentration acids is to dilute them.
