Students can spot the exact moment a single drop causes a permanent faint colour change (such as phenolphthalein turning from clear to a lasting light pink), which stops them overshooting the endpoint.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 150mm x 150mm (tile face) | 16cm x 16cm x 1.3cm (packaged size)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.285kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Sublimation-ready glazed ceramic\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SmartLabs","offers":[{"title":"White tile 150mm x 150mm","offer_id":49042102616217,"sku":"WT-001","price":5.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0569\/3584\/1945\/files\/white-tile-150mm-x-150mm-4243736.png?v=1789758373","url":"https:\/\/smartlabs.co.za\/products\/white-tile-150mm-x-150mm","provider":"SmartLabs","version":"1.0","type":"link"}
