In chemistry, bases are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor, and/or contain completely or partially . Explain. Identify whether a solution of each of the following is either acidic, basic or neutral. It can convert pH to H+, as well as calculate pH from the ionization constant and concentration.
