Why does a buffer solution will change in pH upon addition of acid or base?
Buffering compounds are weakly ionised, addition of hydrogen or hydroxide ions (in modest amounts), shift the degree of ionisation of the buffer which produces an increase or decrease in the hydrogen or hydroxide ions provided by the buffer itself. This change in ionisation of the buffering compound approximately compensates for the addition.
Is there much oxygen and hydrogen in the air?
Air contains abundant oxygen and trace amounts of hydrogen.
Does ammonia contain hydroxide ions?
No. Ammonia has the chemical formula NH3. However, when dissolved in water ammonia will form small amounts of ammonium hydroxide. NH3 + H2O --> NH4OH
What causes potassium to catch fire?
Let's look at the equation for the reaction of potassium and water: Potassium + water --> potassium hydroxide + hydrogen The reaction is fast and generates sufficient heat (it is exothermic) for the hydrogen gas produced to react with oxygen in the air. The presence of potassium gives the flame a lilac colour as the hydrogen burns. In comparison, lithium and sodium are less reactive so the reactions are slower and produce less heat so the hydrogen gas produced does not ignite. So, the potassium does not burn, the hydrogen does!
WHAT contains carbon hydrogen and oxygen with small amounts of oxygen?
Carbohydrates.
When water ionizes it produces equal amounts of hydrogen and hydroxide ions which can re associate with each other?
Yes, due to same reason water is neutral and its pH value is 7.
What produces Large amounts of energy within the Sun?
Fusion of hydrogen.

What is occurring when a piece of potassium metal ignites in a beaker of water?
The potassium reacts with water to produce potassium hydroxide, hydrogen gas, and large amounts of heat. The heat ignites the hydrogen which in turn ignites the potassium.
Is amonium hydroxide a liquid metal?
Ammonium hydroxide is neither a metal nor a liquid. It is an compound consisting of the nonmetals nitrogen, hydrogen, and oxygen that only exists in small amounts in solutions of ammonia dissolved in water. The only liquid metal is mercury.
Why do you see flame in reaction between sodium and water?
The sodium an water react to produce sodium hydroxide, hydrogen gas, and large amounts of heat. This heat ignites the hydrogen which in turn sets the sodium on fire. Sodium burns with a yellowish flame.
When sodium is put in water it produces a golden flame why?
Metallic sodium reacts with water producing sodium hydroxide, hydrogen gas, and lots of heat. The hydrogen gas mixes with air and the heat ignites this mixture. Small amounts of sodium atoms are carried up into the flame, where the heat ionizes them. As these excited ions relax back to their ground state they emit yellow/golden color photons, giving the flame its hue.
Why can you only get certain amounts of isotopes such as hydrogen having none or 1 or 2 neutrons and not 3 or above?
heavier isotopes can be produces but their halflives are in the microsecond or shorter range.
What can neutralize acids?
NaOH + HCl -> NaCl + H2O Mixing with similar amounts of base. Here we have sodium hydroxide + hydrochloric acid the produces a salt an water.
What state produces major amounts of corn?
Iowa
How do hydrogen isatopes differ?
they have different amounts of neutrons
Is there much oxygen and hydrogen in the air?
Air contains abundant oxygen and trace amounts of hydrogen.
