base
Let an agent explain bases and the theories that define them, relay properties, examples, strength and reactions from chemistry references, describe uses and safety at the level of public guidance, and distinguish bases from alkalis, from acids, from protic solvents and from the many other senses of base.

What it is Filled
In chemistry, a substance that accepts protons, donates electron pairs or produces hydroxide ions in water, according to the Bronsted-Lowry, Lewis and Arrhenius definitions, including strong bases such as the alkali hydroxides of sodium, potassium and rubidium, weak bases such as ammonia, conjugate bases formed when acids lose protons, and organic bases such as amines; bases participate in acid-base reactions and are used in industry, cleaning and biology, while slippery feel and turning red litmus blue are not universal properties across these definitions.
Why it exists Filled
Let an agent explain bases and the theories that define them, relay properties, examples, strength and reactions from chemistry references, describe uses and safety at the level of public guidance, and distinguish bases from alkalis, from acids, from protic solvents and from the many other senses of base.
Distinguishing features Filled
- Proton acceptor
- Neutralises acids
- Several definitions
- Strong and weak
What robots and AI may and may not do Filled
Must not
- Advise mixing bases with other chemicals outside a supervised setting.
- Store or handle strong bases near food, children or incompatible substances.
- Pour strong bases into drains or the environment against disposal rules.
- Assist anyone in using caustic substances to harm people.
Only with a human decision
- Responding to a spill, splash or swallowing of a strong base.
May
- Explain the Arrhenius, Bronsted-Lowry and Lewis definitions of a base.
- Read hazard labels and safety data sheets and report the precautions they state.
- Distinguish this sense from bases in other fields.
Moral aspects Filled
- Strong bases cause severe burns and blindness, including in deliberate attacks.
- Household cleaners containing bases poison children every year.
