### ICE

How do you know when to use an ICE table? do you have to use when if given Ka or Kb?

### Re: ICE

You use the ICE table when trying to find a missing concentration. Ka and the initial concentration of the reactant are usually given.

### Re: ICE

You use an ICE table to solve for concentrations so usually you will be given K.

### Re: ICE

You usually have to use the ICE table when you only have the initial concentrations or you need to calculate the equilibrium concentrations. If Ka or Kb are given with some concentrations, then you are usually using the ICE table and the Ka or Kb values to find any missing concentrations.

### Re: ICE

When you are given Ka or Kb it is a good sign that you will end up using an ice table. This is because it gives the ratio of products over reactants at equilibrium, so you can use it to find missing concentrations.

### Re: ICE

Use ICE when you are given K and need to find the equilibrium concentrations of the molecules.

### Re: ICE

When you are given K(Kc, Ka, Kb, etc.) and need to find the equilibrium concentrations of the molecules, you use the ICE table to find the unknown equilbrium concentrations.

### Re: ICE

You would use an ICE table when you are trying to find one of the concentrations that is unknown. You will usually be given a K value.

### Re: ICE

ICE tables are used when you're looking for the equilibrium concentration of a certain reactant or product, and are given the initial concentration. With an ICE table, using a quadratic formula, you can easily solve for the given concentration.

ICE table are used in a problem when you're trying to find the equilibrium concentration.

when they give you a concentration and ask for equilibrium concentration

### Re: ICE

An ICE chart is used whenever you're asked to calculate what the effect was of a reaction on the affected substances' concentration or pressure in their container.
Notice how whenever you write the "E" (equation) part of the ICE chart that you write products over reactants? Well, the whole "+x" or "-x" part is accounting for the change in the balance (at equilibrium, for example) because of the fact that they reacted under whatever given conditions.

You may also need to use an ICE table when asked for the PH. Indirectly they are asking for the [H3O+] concentration to find the PH.

You use an ICE table when you are looking for the concentration of something. Ka helps to solve for x

### Re: ICE

You would set up an ICE table when given some significant value (ie. pH, pOH, K, etc.) and want to find the concentrations of the reactants and products in a chemical reaction. Usually questions tend to ask for the equilibrium concentrations after giving a K value and one initial concentration.

### Re: ICE

You use an ICE table when you need to find missing concentrations (most likely trying to find equilibrium concentrations given an equilibrium constant). You have an initial concentrations row, where you put your initial concentrations for each species in the reaction. The change is how much the initial concentration will change (you should use a variable modified by the stoichiometric coefficient). The final concentrations are the sum of the initial concentrations and the initial concentrations. To find equilibrium concentrations, plug in the final concentrations (with variables) into the equilibrium formula and set it equal to the equilibrium constant of the reaction. Find the missing variable and plug it into the final concentrations (with variables) to find the final concentrations of each species after the reaction reaches equilibrium.

When asked to calculate the equilibrium concentrations of the products or the reactants of a reaction we use the ICE table

### Re: ICE

It's mainly used to find the unknown value of a concentration. It's also based on what values you're given but you'll mainly be given the concentrations of the reactant and want to solve for the products.

### Re: ICE

you need two values! these are usually only one starting concentration and K OR one starting concentration and one ending concentration

### Re: ICE

You use an ICE box to find an unknown concentration. That can be either initial concentration or equilibrium concentration. When you are given Ka or Kb that will be used to find one/more than one of the equilibrium concentrations
