There is much talk about the oceans becoming more “acidic” due to manmade global warming. This is quite remarkable as the oceans are actually alkaline having a pH of about 8. You may recall that the measure of acidity and alkalinity has water neutral at the level of 7. Anything above 7 is base or alkaline whereas anything below 7 is acidic. Thus a small change in pH from a little above 8 to a little below 8 just means the oceans are becoming closer to neutral not more acidic. This is an important consideration when teaching this subject to children and others. Let’s get it right.
