Identify the substance that each property describes.

only acid
only base
both acid and base

feels slippery

tastes sour

conducts electricity

conduct electricity -- NaCl

feels slippery -- diamond

taste sour -- vinegar  because the taste sour the litmus paper turn red it is acidic  acid

only acid -- hydrogen ions

only base --- caustic soda

both --- aluminum hydroxide

Explanation:

Explanation:

Acids are the substances that have pH less than 7. Acids are sour in taste and when dissolved in a polar solvent like water they dissociate into ions. Hence, they are able to conduct electricity.

Whereas bases are the substances that have pH more than 7. Bases are slippery in nature and when dissolved in a polar solvent like water they dissociate into ions. Hence, they are also able to conduct electricity.

Hence, we can conclude that the given substances with each property are described as follows.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
