Concentrated or strong bases are caustic. Changing the indicator color from red to blue changes the color of the litmus paper. It can accept protons from proton donors. It contains OH− ions. Acids react vigorously with them. They are slippery to the touch. When dissolved in water, they c...

An acid is a chemical species that turns the color of the naturally occurring blue litmus paper into the red. In contrast, a base changes the color of red litmus paper into blue. Answer and Explanation:1 According to Arrhenius's definition, a base is a species that furnishes hydroxide ions...
Bases turn red litmus paper blue, have a bitter taste, and have a pH of greater than 7. Compare acid. 2. Mathematics a. The side or face of a geometric figure to which an altitude is or is thought to be drawn. The base can be, but is not always, the bottom part of the ...
How does a litmus paper help in a chemistry experiment? Why was phenolphthalein a good indicator to use for determining the equivalence point between the unknown weak acid and strong base? What is the color of a phenolphthalein indicator in an acidic solution? Wha...
