If you were to test a small sample of soda lime with
universal indicator would it
register a pH above or
below 7? Explain your answer

The soda contains CO2 that is dissolved CO2 reacts with water

CO2+H2O--->H2CO3

to form carbonic acid

this is a weak acid but it gives protons to water

H2CO3+H2O-->-HCO3+H30+

pH=-lg[H3O+]

[H3O+] is the molar concentration

Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
