For a non 1:1 weak electrolyte, explain why the definition of equivalent conductance no longer holds. Explain how holes conduct electricity. Explain how fission can be used to generate electricity. Why do some electrochemical cells employ inert electrodes such as platinum? Explain why some elect...
I also saw why I can suddenly become irritable at a moment’s notice, and why I react so intensely to certain chemicals and fumes. It was a relief to have this new understanding: things made sense to me in a way they never had before, plus I had some new solutions I could rely on...

Why should the colorimetric titration of a weak acid and weak base not be done in the laboratory? Give two examples of weak acids. What happens when an acid meets a base? Define alkalosis and explain how it relates to electrolyte imbalances and/or acid-base...
moisture in the air to form a water film. This water film contains a small number of hydrogen ions and hydroxide ions and also dissolves oxygen and other gases. An electrolyte solution is formed which forms a myriad of tiny primary cells with iron and a small amount of carbon in the ...
Severe or prolonged overcharging can also ruin a battery by boiling away the electrolyte in the cells. If your battery is getting weak, keeps running down or won't hold a charge very long, you should have the battery tested to see if it is good or bad. SeeBATTERY TESTINGfor details. ...
