For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8. Pure water is neutral. But when chemicals are mixed with water, the mixture can become either acidic or basic. Examples of acidic substances are vinegar and lemon juice.
For Office 2013, the lineup of packages available through retail channels remains the same, but Microsoft is bumping prices significantly. Office Home & Student, which includes Word, Excel, PowerPoint, and OneNote, will cost $140, up 17% from the current $120. Office Home & Business, which includes the above apps plus Outlook, will go for $220, up 10% from the current price of $200.
As you've no doubt heard by now, Microsoft just announced Office 2013 and The New Microsoft Office suite. Not announced: pricing. Call it a hunch, but I suspect Microsoft will charge at least as much for Office 2013 as it does for Office 2010. After all, the new suite is chock-full of new features, giving Microsoft ample justification for keeping prices the same -- or even raising them.
