Knowledge Clash Transcript: DPP Legislator Chen Ying Questions EPA Director on Slag 'pH' and Gets Countered That Solids Can't Be Measured!

This article records a controversial exchange between DPP Legislator Chen Ying and EPA Director Wei Guo-yan regarding slag's pH value. Legislator Chen questioned whether a pH=12.5 strong alkali substance spread on ground would cause pollution concerns, while Director Wei repeatedly emphasized 'slag is a solid with no pH value—it must dissolve in water to be measured.' Both sides became trapped in circular argument due to differing basic chemistry concepts. The article comments sarcastically that the legislator's refusal to understand professional explanations was the source of conflict.
