    How Do You Calculate the Acid Dissociation Constant?

    I'm sorry, I don't know how to do that. I understand what you are saying though. I just want to fully understand how to do the question. I know you are saying that from knowing the hydrogen ion concentration, I will be able to figure out how much the acid is dissociated. I am just having...

    Is Releasing Hydrogen Ions the Defining Characteristic of Arrhenius Acids?

    Thank you. I was trying to think of things to disprove the other answers to validate my answer :)

    How Do You Calculate the Acid Dissociation Constant?

    A 0.1 mol/L aqueous solution of weak monoprotic acid (contains one ionizable hydrogen atom) has a hydrogen ion concentration of 0.001mol/L. The value of Ka is: a) 10-6 b) 10-2 c) 10-3 d) 10-5 I took 0.001 and divided by 0.1 to get 10-2 and I also multiplied them together to get 10-5...

    Is Releasing Hydrogen Ions the Defining Characteristic of Arrhenius Acids?

    An Arrhenius acid a) in an ionic compound that contains hydrogen atoms b) produces an aqueous solution whose pH is greater than 7 c) releases hydrogen ions in aqueous solution d) is always a neutral molecule I know that c) is true and d) is false. However, I don't know if a) and b)...

    Chem - freeze drying & equilibrium

    Okay, but I am not sure how LeChatelier's principle fits in here. Anyone have any ideas? The only thing I can think of is that the freeze drying process is kind of exploiting how a system reacts to different temps and pressures by adjusting. The adjustment would be consistent with LeChatelier...

    Chem - freeze drying & equilibrium

    So I have to use Le Chateliers principle to expalin why low pressure is used in the freeze-drying process (eg in making instant coffee) So here is what I know so far: in freeze drying, they turn solid water right into a gas basically removing all moisture from the food so it keeps for a very...
