What happened to Ask Jeeves?
Ask Jeeves was a character-driven search engine, if ever there was one. Ask Jeeves lasted until roughly 2005, when it was rebranded as Ask.com. The company attempted to invade Yahoo Answers’ territory by focusing on a real-person Q&A site, but Ask.com ended its foray into search engineering in 2010.
How much is Ask Jeeves worth?

What is the purpose of DuckDuckGo?
DuckDuckGo (also abbreviated as DDG) is an internet search engine that emphasizes protecting searchers’ privacy and avoiding the filter bubble of personalized search results.
What is the relationship between pH and water?
pH and Water. pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a very important measurement concerning water quality.
Which is the correct definition of the pH scale?
1 pH. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH +, in a solution. 2 p [H] This was the original definition of Sørensen in 1909, which was superseded in favor of pH in 1924. 3 pH indicators. 4 Non-aqueous solutions. 5 Unified absolute pH scale.
What do you use to check the pH of water?
Litmus paper, which can be found at pet-supply stores (to check the pH of aquariums) is simply a strip of paper that, when a sample of water is dropped onto it, turns a certain color, giving a rough estimate of pH. Excessively high and low pHs can be detrimental for the use of water.
How is the pH of aqueous solution determined?
In chemistry, pH (/piːˈeɪtʃ/) is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. Pure water is neutral, at pH 7 (25 °C), being neither an acid nor a base.
