How is a universal indiciator used to estimate the
The universal indicator changes the colour of the solution. The solutions colour can be matched against a PH scale. This gives a rough indication of the PH.
What type of base is an alkali?
An alkali is a soluable base.
What is the equation for neutralisation?
acid + base -> salt + water
Metal Oxides and Metal hydroxides neutralise acids because they are bases
Carbonates neutralise acids to give water, a salt and carbon dioxide
What two things in a solution that could contain h
acid and alkali
