Lime water in the presence of carbon dioxide turns into milky white in color.it's true
A)true, Sulphuric acid is a strong acid.
B)true, NaCL(sodium chloride) is a base
dilute means adding water to acid.concentrated means pure
because acids contain H+ ions
they contain OH- ions. they are bad conductors of electricity
HCl :blue to red , red no change
NaOH :red to blue

by electrolisis of water we can prove that acids are good conductors of heat.
