water and oxygen is even more corrosive. Virtually all elements burn in an atmosphere of oxygen‚ or an oxygen rich environment. In the presence of water and oxygen (or simply air)‚ some elements— sodium—react rapidly‚ even dangerously‚ to give the hydroxides. In part for this reason‚ alkali and alkaline earth metals are not

I choose is Sodium hydroxide (NaOH) and for the indicator to show that this will make it neutral is the Universal Indictor I choose that indicator because it has a wide color spectrum when being neutralized. Predictions How much base do you think do you think it will take to neutralize 5mL of acidified lake water? Why? I believe that it will take a little less then 5mL to neutralize it because it will rapidly dissolve and neutralize it. I also know because sodium hydroxide is very responsive

base is a substance that changes red litmus paper to blue. Most of the bases Used in the in the laboratory are soluble in water. These bases are called alkalis. Any compound that begins with the name of metal and is followed by the word oxide or hydroxide is a base. Properties of Base They have a bitter taste. They have slippery touch. They conduct electrically. It turns red litmus to blue. It turns colorless
