writing equations

Postby 905084274 » Thu Jan 17, 2019 9:22 pm

If you were to be given a base - such as Bf3(OH)- and you knew that you needed to make an equation to solve. How would you set it up? What is the rule of thumb and how to you know when to add water?

If you are finding the pH or pOH, the best place to start is to figure out if it will produce H3O or OH. Once you know that you can figure out if you are missing an element that would have to come from water. If it is an acid you will most likely always have to add water to write out the equation, for bases you might not have to, like in your example.
