**what is the ph of a 0.020 m ba(oh)2 solution?** This is a topic that many people are looking for. **savegooglewave.com** is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, ** savegooglewave.com ** would like to introduce to you **pH and pOH of Ba(OH)2**. Following along are instructions in the video below:

Now were going to move to the bases and the first cover base runner runner is a strong base a third type of fall so in this one is us to determine the ph and the poh of a point. Oh one one two molar barium hydroxide solution. So now we know barium hydroxide is a strong base thats our first clue remember.

It is a alkaline earth metal plus and hydroxide right a definition of our strong base so from here we list we can start with either ph or. Poh but lets start with the. Information we have given we had 001.

One two molar barium hydroxide. So remember from our rules. Point no one 1 2.

Molar will equal the concentration of barium hydroxide right. But that means that the hydroxide concentration is going to be two times. That number because we have two alright and so were going to multiply our molarity by two and that is simply going to be so dont forget that the alkaline earth strong bases have this two not two has to be accounted for in the oah concentration.

When we do our muller. But after that the problem is still the same so we have h concentration. Now there are several ways we can work to get to the first way to get to ph were going to need is the negative log of hydronium right and poh is negative log of oh h so we know those definitions now right now if you wanted to find poh we could simply take negative log of 002 to 4.

And that would give us poh and that would be around three point seven two we can also keep going and work it another way to find and then we could take if we have poh we can take ph. We know is going to be 14 minus that number because we know 40 nasty. Some of those numbers so ph when we go from there is simply going to be 14 minus 37.

T. And thats when we get the 10 22. That is one way to work the problem another way to work.

The problem is we could have taken p. Instead of going to poh directly. We could have taken kw oh h.

Concentration to get hydronium h. Plus concentration because remember concentration of oh difference. A plus equals kw.

We could have solved for h both conversation concentration there and that would have been four point four six four times molar when we solved for this and then we could have taken to get ph negative log of that hydronium so its going to be negative one and our number would have still been the same two point two eight whatever in ph. Then we would have done poh with 13 with three point seven to both of these ways are valid ways of working. The problem and you can choose whichever way is easier for you.

But remember this is a strong base. So we dont have a nice table or a ka value for edith. .
