How do you make a 10 percent aqueous solution of potassium hydroxide?
To make a 10 percent aqueous solution of potassium hydroxide, you would dissolve 10 grams of potassium hydroxide in enough water to make a total solution volume of 100 mL. This solution would be considered a 10 percent concentration by weight. Be cautious when handling potassium hydroxide as it is a caustic substance.
How many moles are in 4.75g of sodium hydroxide?
To find the number of moles in 4.75g of sodium hydroxide, you first need to determine the molar mass of sodium hydroxide (NaOH), which is about 40g/mol. Then divide the given mass (4.75g) by the molar mass to obtain the number of moles: 4.75g / 40g/mol = 0.119 moles of NaOH.
A science teacher added the reactive metal potassium to water. The metal formed a ball shapeon the surface of the water and the gas given off burned with a pop. Name the gas given off.?
The gas given off is hydrogen gas. When potassium reacts with water, it forms potassium hydroxide and hydrogen gas. The pop sound is due to the ignition of the hydrogen gas.
How many moles of sodium hydroxide are in 40 grams of sodium hydroxide?
To find the number of moles in 40 grams of sodium hydroxide, you first need to calculate the molar mass of NaOH. The molar mass of NaOH is about 40 g/mol. Then, you divide the given mass by the molar mass to get the number of moles. So, 40 grams divided by 40 g/mol is equal to 1 mole of NaOH.

Which gas is given off when potassium permanganate is broken down?
Oxygen gas is given off when potassium permanganate is broken down. Potassium permanganate decomposes into manganese dioxide, potassium hydroxide, and oxygen gas when heated.
Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.
What is the name given to a soluble base?
A soluble base is called an alkali. Alkalis are substances that can neutralize acids, forming salts and water. Examples of soluble bases include sodium hydroxide and potassium hydroxide.
What name is given to the chemical with the formula NaOH?
Sodium hydroxide
If Potassium Manganate is heated what gas is given off?
It turns dark green and lets of oxegeon decreasing the mass
What name is given to substances that can neutralise acids?
Substances that can neutralize acids are called bases. Bases can react with acids to form salt and water through a chemical reaction called neutralization. Examples of bases include sodium hydroxide, potassium hydroxide, and ammonia.
When hydrochloric acid and potassium hydroxide are mixed what gas is given off?
I have no idea. The products of that reaction are water (not a gas at room temperature) and potassium chloride (not a gas at room temperature).
When potassium carbonate is heat what gas is given off?
When potassium carbonate is heated, carbon dioxide gas is given off. Potassium carbonate decomposes to form potassium oxide and carbon dioxide.
What alkali is the best neutralise hydrochloric acid?
Any Group(I) metal alkali Lithium hydroxide (LiOH) Sodium hydroxide (NaOH) The commonest) Potassium hydroxide (KOH) Rubiudium hydroxide (RbOH) Caesium hydroxide (CsOH) Also Group(II) metal hydroxides #e.g. Calcium hydroxide ( Ca(OH)2 ). The will all neutralise hydrochloric acid Here is the general eq'n MOH + HCl = MCl + H2O ( where 'M' is the given metal).
Supply the missing products in the following chemical equation KClaq NaOHaq?
The missing products in the given chemical equation KClaq + NaOHaq are NaClaq (sodium chloride) and KOHaq (potassium hydroxide).
How many moles in 20g of sodium hydroxide?
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
