Demonstrations with dry ice: explore changes of state and neutralisation reactions

Solid carbon dioxide (dry ice) can enhance your teaching in many ways. These three visually striking experiments come with full instructions and technician notes, download from Education in Chemistry: https://rsc.li/3YawOuS Demonstrate the sublimation of carbon dioxide and a colour-change neutralisation reaction accompanied by cloud-filled bubbles that spill a mist of water onto the desk. The final demonstration compares strong and weak bases and helps explain why indicators are not suitable for titrating weak acids with weak bases. Use the demonstrations in your lessons with 11–14 and 14–16 year-old learners. Also great for public or outreach events.
