Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given out when sodium hydroxide reacts with a metal.
What information is necessary to determine the pH of a solution when you given hydroxide ion concentration?
You will need Kw to determine the concentration of hydrogen ions and You will need the formula pH = -log[H+]
Which gas is always given off when an acid solution is electrolysed?
Hydrogen
What ion is given off by acids?
Hydrogen ions are present in acids, hydroxide ions are present in bases.
What name is given to substance the decrease the concentartion of hydrogen ions in solution?
A base

How do you make a 10 percent aqueous solution of potassium hydroxide?
Weigh 10g of the given sample and dissolve it in 100ml of water, it forms a 10% solution of that sample.
What is the reaction between calcium and water?
Calcium reacts with water to form calcium hydroxide and hydrogen gas. Calcium is oxidised and hydrogen is reduced, so it is a redox reaction. It is also a displacement reaction as hydrogen in water is displaced by calcium.
What is the concentration of hydronium ions in a solution given that the concentration of hydroxide is 2.31 x 10 -4?
4.33 X 10^11
How many molecules are in 100 L of potassium hydroxide solution at STP?
The number of molecules in a given volume of solution depends on the concentration of the solute. Because the concentration is not provided, this question has too little information to answer.
What is simply a measure of how many H positives there are in a solution?
The concentration of H+ ions is given by pH, a term that stands for potential Hydrogen (it's called potential hydrogen because hydrogen ions can potentially become hydrogen gas).
Given a 5 Molar sodium hydroxide Calculate how much 5 Molar base you need to make a 100 mL of a 1 M solution?
20 ml
When electrolysis occurs in salt water chlorine and hydrogen are given off what happens to the sodium and oxygen?
The electrolysis of brine (salt solution) involves the breakdown of sodium chloride and water into its basic ionic components: sodium, hydrogen, chlorine and hydroxide ions. The hydrogen and sodium are both positively charged ions, and are attracted towards the negatively charged electrode, where the least reactive of the two ions - hydrogen - gains an electron to become an uncharged hydrogen atom. Sodium is more reactive, so it remains in the electrolysis chamber (sometimes called a diaphragm cell) as an Na+ ion. The chloride and hydroxide ions are negatively charged, so they are attracted to the anode, where the chloride is liberated as a chlorine molecule, because it is the least reactive of the two anions. The hydroxide remains in the container as an OH- ion. The chlorine is used to sterilise swimming pools and to make PVC plastics. The hydrogen is used in the process of making margarine. Meanwhile the sodium and the hydroxide ions join together to form sodium hydroxide, which is a widely used bleach. It is also used in the manufacture of paper and soap. The equation for the electrolysis of brine is: 2NaCl + 2H2O --------> Cl2 + H2 + NaOH
