@aracelyssantana3789 Год назад

so diffusion is trying to reach equilibrium. and the process is called osmosis - the movement from higher concentration to lower.

Isn’t it ‘…higher water potentioal to a lower water potential’? I saw on some mark schemes of Edexcel IGCSE papers that they don’t accept the answer if you don’t say water potential.

@ariim3232 2 года назад

ik u typed this comment 5 months ago alr,but um,I am pretty water concentration is the same as water potential, if not and it has to be water potential for igcse then I guess it just has to be :)

its a partially permeable membrane so big molecules can't diffuse across

@_AmelieThomas 6 месяцев назад

AQA defines osmosis as 'the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane.' But the video says it's from high to low concentration? Correct me if I'm wrong, my mocks are in a couple days and I really need to know quickly!!

@Tas_ren 5 месяцев назад

late but whenever this comes up go for the first one since its directly from the spec + my teacher also tells me to write dilute solution rather than the other one
