Study Notes
- Many things contain acids, including some foods.
- Foods containing acids typically taste sharp and sour due to weak citric acids.
- Common lab acids include hydrochloric, sulfuric, and nitric acids.
- Strong acids are corrosive and can cause chemical burns by dissolving skin.
- Diluting acids with water reduces their danger, but they remain irritants.
- Bottles containing hazardous substances have warnings displayed on them.
- Many cleaning products contain alkalis like sodium hydroxide, a strong and dangerous alkali.
- Strong alkalis dissolve skin, causing a soapy feel and chemical burns.
- Water dilutes alkalis, reducing their danger.
- Common lab alkalis include sodium, potassium, and calcium hydroxide.
- Acids and alkalis neutralize each other when mixed.
- Acidity or alkalinity is a chemical property of a substance.
- When handling acids and alkalis:
- Stand up to prevent spills onto yourself.
- Wear safety glasses to protect your eyes.
- Place bottle tops upside down on the surface to prevent contamination.
- Replace bottle tops immediately after use to prevent spills and misidentification.
