Jack Cunningham Basketball Wiki, It is probably a bit alkaline in solution. acidic: NH4Cl no: (C2H5)2NH True: Adding more [CH3NH3+] to the initial buffer solution will decrease the pH. State whether each of the following aqueous solutions would be acidic, basic, or neutral. 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 .
