Final answer:
The assertion that acids and alkalis are limited by their hazardous, corrosive natures is true. Strong acids and bases can cause chemical burns, with bases generally being more dangerous. Acids and bases can neutralize each other when mixed.
Step-by-step explanation:
In response to the question about the properties of acids and alkalis, the statement that acids or alkalis are limited in their application by their corrosive and hazardous nature is true. These substances are often very reactive and can cause harm upon contact with skin or ingestion. Corrosive compounds, such as hydrochloric acid and caustic bases like some household cleaners, can cause chemical burns. The harmful effects of strong acids and bases, especially in concentrated forms, are due to their ability to decompose proteins and lipids by amide and ester hydrolysis. However, while our bodies are generally more capable of handling the ingestion of certain acids, such as those in citrus fruits and vinegar, strong bases are considered more dangerous because of how easily OH− ions can remove H+ from tissues.
According to the Arrhenius definition, acids are substances that produce H+ ions in solution, while bases produce OH− ions. This concept applies specifically to aqueous solutions. It is also important to note that acids and bases can indeed mix together and, in fact, neutralize each other, resulting in a solution that is closer to neutral pH than either the acid or base alone.
