The pH scale goes from 1-14

i want to know if baking powder is a alkaline or acid.]]> 2018-02-12 13:11:20 UTC https://padlet.com/francisa57/k4727mw9ohs3/wish/230560156 harvey and the lads and chloe https://padlet.com/francisa57/k4727mw9ohs3/wish/230560184 the ph scale goes from 1 to 14 and they have different  colours to represent them
Today i learnt that cola was an acid. 

i learnt how to peform different chemical procceses i want to find out about super acids
