What does k plus h2o make in chemistry?
The reaction between potassium (K) and water (H2O) typically results in the formation of potassium hydroxide (KOH) and hydrogen gas (H2). This reaction is highly exothermic and can cause the hydrogen gas produced to ignite.
What happens when you mix sulphuric acid and potassium hydroxide liquid?
This would produce an energetic reaction with a lot of heat, and the product would be water and potassium sulfate (as long as the molar quantities of the reactants are the same, otherwise you will have leftover sulfuric acid or leftover potassium hydroxide).
How do you precipitate magnesium ion out of 50-mL of 21 M solution of magnesium nitrate?
To precipitate magnesium ion, you can add a precipitating agent such as sodium hydroxide (NaOH) to the magnesium nitrate solution. This will cause magnesium hydroxide (Mg(OH)2) to form as a precipitate. You can then filter the solution to separate the precipitate from the liquid.
Why is magnesium hydroxide a better antacid than sodium hydroxide?
Sodium hydroxide is a strong base (fully dissolves in water) and is highly caustic. If it touches the skin it can cause severe chemical burns. Swallowing it can result in severe damage, often permanent, to the digestive tract and death. Magnesium hydroxide is a weak base (minimally dissolves in water). It cannot cause the damage that sodium hydroxide does.
Products that contain magnesium hydroxide frequently cause?
Products containing magnesium hydroxide can commonly cause diarrhea due to its laxative effect. Excessive use can lead to electrolyte imbalances and other gastrointestinal issues. It is important to use products containing magnesium hydroxide as directed to avoid these side effects.
What are the word and chemical equation for the reaction that cause potassium to tarnish?
The word for the reaction that causes potassium to tarnish is oxidation. The chemical equation for this reaction is 4K + O2 -> 2K2O.
What part antacid play in a neutralization reaction?
An antacid you'd take for indigestion contains one or more weakly alkaline chemicals, such as aluminum hydroxide, magnesium hydroxide, calcium carbonate (chalk) or sodium bicarbonate (baking soda). They react with excess hydrochloric acid in the stomach to increase the pH -- making the stomach contents less acidic. Alkalis like sodium or potassium hydroxide -- lye -- are far too strong and would cause serious or fatal injury. Overuse of antacids can cause serious electrolyte imbalances and other problems. Consult your doctor.
What type of reaction happens when potassium is placed in water?
When potassium is placed in water, it undergoes a highly exothermic reaction, producing hydrogen gas and forming potassium hydroxide (KOH) as a product. This reaction is also highly reactive and can result in the ignition of the hydrogen gas produced.
What is the product of pottasium with water?
If a piece of Potassium is dropped into a beaker of water it whizzes around on the surface of the water. The reaction is so vigorous that the heat of it causes the Potassium metal to metal. It 'fizzes' and the heat generated can often cause the Hydrogen, that is produced by the reaction, to ignite with a lilac colour flame. Larger pieces of Potassium may even explode due to the vigor of the reaction. 2K + 2H2O ----> 2KOH + H2 (gas)
Will milk of magnesia cause positive benzo on drug screen?
No. Magnesium hydroxide is the only thing that's in it.
Why is magnesium hydroxide used as an antacid instead of sodium hydroxide?
Magnesium hydroxide is favored as an antacid over sodium hydroxide because it has a lower risk of causing systemic alkalosis when used in moderate doses. Additionally, magnesium hydroxide can also act as a laxative, providing additional benefits for individuals with constipation. Sodium hydroxide, on the other hand, is a strong base that can lead to complications if ingested in significant amounts.
What happens when potassium hydroxide is kept near a potted plant?
Potassium hydroxide, being a strong base, can cause harm to the plant if it comes in contact with its roots or leaves. It can disrupt the plant's pH levels and damage cell structures, potentially leading to wilting or death of the plant. It's important to keep potassium hydroxide away from plants to avoid any negative effects.
