why is H2SO4 considered as strong acid? What colour does it give with phenolphthalein and methyl orange?​

H2SO4 (sulphuric acid) is considered a strong acid because it's H+ ions completely dissociates or ionizes in a water. When reacted with phenolphthalein is colourless because phenolphthalein doesn't react with acids, only strong bases and when reacted with methyl orange, it changes from orange to red.

Explanation:

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
