What chemical should be added to neutralize hydrochloric acid?
Add the correct amount of an Alkali, such as Sodium Hydroxide. Use an indicator to find out when it has been neutralized, such as phenolphthalein (however you spell it) or Universal Indicator.
Reactions of halogens with water and sodium hydroxide?
the halogen dissociates in water to form it's respective acid or acids. in sodium hydroxide, since all halogens are above hydroxides in the electronegative series, they displace the hydroxide to form the sodiumhalide.
How do you know a solution is a neutral?
because it will either be green,blue,yellow
Is oxygen in both lime and lye?
Yes, Lime is CaO (calcium oxide) and lye is NaOH or KOH (sodium or potassium hydroxide). In the above formulas O represents oxygen.
Why does sodium bi sulphate solution have a pH less than 7 but sodium acetate solution have a pH above 7?
Bisulfate is HSO4- anion, which is weakly acidic in nature (capable of protolysis, proton donation) while the acetate anion (CH3COO-) is basic only.
What is the pH colour of sodium hydroxide?
Sodium hydroxide is a colourless liquid, and it is also called as caustic soda.
Does sodium hydroxide make hair fall out?
partially, depending on the percentage of the sodium hydroxide, if its above 30% it is possible.
Mixing acetone and sodium hydroxide?
oxidation-reductionWhat type of a reaction occurs when a sodium hydroxide solution is mixed with an acetic acid solution?The answer above is wrong. The correct answer is acid-base neutralization
What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
What happens when you mix water and sodium?
you get salt water which is called sodium hydroxide You get sodium hydroxide as stated above but NOT salt water as this is sodium chloride in water which has the formula NaCl and not NaOH.
What products would you get when you bubble chlorine gas through a sodium bromide solution?
You would get Sodium Chloride and Bromine. This is because Chlorine is a more reactive group 7, (halogen), element that bromine, we know this because it is above bromine in the periodic table group, it is therefore more electronegative. When the reaction occurs, the Chlorine displaces the Bromine and the solution turns brown.
What is a solution that contains more hydroxide than hydrogen?
It is a basic solution, pH above 7
Why does hydroxide act as a base in sodium hydroxide and as an acid in acetic acid?
Hydroxide is a Bronsted-Lowry base, meaning that it accepts protons from other substances. When sodium hydroxide ionizes, it forms the following: NaOH + H2O --> Na+ + OH- In the Arrehnius definiton, it increases the amount of hydroxide. In this case, sodium hydroxide does so. Also, when measuring pH, NaOH gives an alkaline reading, meaning that the pH is above 7. This is due to the decrease of hydronium and the increase of hydroxide. Sodium Hydroxide is not in Acetic Acid. Acetic Acid is CH3COOH (also known as HC2H3O2).
What is the pH of sodium hidroxide?
Sodium hydroxide is alkaline and so its pH must be above 7. It is not a strong base so its pH may be 9 approximately.
What is meant by Sodium acetate is a basic salt?
Sodium acetate is called a basic salt because a solution of it in initially pure water has a pH value well above the neutral value of 7. This occurs because acetate ions when dissolved in water must come to an equilibrium in the ionic reaction C2H3O2-1 + H2O <-> C2H4O2 + OH-1 and sodium ions when dissolved in water must come to an equilibrium in the ionic reaction Na+1 + H2O <-> NaOH + H+1. Additionally, water itself must maintain an equilibrium in the ionic reaction H2O <-> H+1 + OH-1. The values of these three equilibrium constants are such that the net result is a higher concentration of hydroxide ions than of hydrogen ions in a solution of sodium acetate. These relative concentrations of hydroxide and hydrogen ions is the defining characteristic of a basic (or alkaline) aqueous solution: Such a relative concentration of hydroxide and of hydrogen ions, although not all the other characteristics of a sodium acetate solution, could be achieved by dissolving an appropriate amount of the base sodium hydroxide in initially pure water.

Which out of hydrchloric acid or sodium hydroxide has a higher pH?
Sodium hydroxide is a strong base with the chemical formula NaOH. Ammonia water is usually a solution of NH3 and H2O mixed together to form NH4OH,. This is usually the stuff people clean with and is also a strong base. Ammonia (the gas) is just NH3.
