Numbuko vs CloudLabs Titration

Numbuko is a colourful and creative way for children to explore number patterns. Informed by research at the University of Edinburgh, UK, Numbuko squares are like many colour rods used in mathematics, but can magically change colour according to the number attached, giving children interactive feedback. Unlike ‘drill and practice’ apps, Numbuko lets children explore number relationships, such as addition, subtraction, fractions, odd and even, and tens and units. Features • Explore fundamental maths concepts for numbers 1-99 • Build and share creative patterns • Add/Remove colour - Encourage predictions • Add/Remove division lines between squares - Encourage/Discourage counting • Save configurations • Find out about the background research Numbuko aims for children to freely explore independently and learn through talk with an adult

This simulator recreates a laboratory with the necessary instruments to perform the titration of different acids, some of which can be polytropic. The acids available for titration are: hydrochloric, acetic, sulfurous, carbonic, phosphoric and hydrobromic. In the course of the practice, you will be able to select different indicators, among them: methyl violet, thymol blue, methyl orange, bromocresol green, methyl red, chlorophenol red, bromothymol blue, phenol red, phenolphthalein, thymolphthalein and alizaraza yellow.
