What is the enthalpy change of neutralisation for strong acid with a strong base?
The enthalpy of neutralization of a strong acid against a strong base is always constant (13.7 kcal or 57 kJ mole-1). It is because in dilute solutions all strong acids and bases ionize completely and thus the heat of neutralization in such cases is actually the heat of formation of water from H+ and OH- ions, i.e., H+ + OH- ---> H2O; ΔH = -13.7 kcal
What is the reaction when you add acids and alkali's?
you create a neutral solution -------------------------------------------------------------------------------------------- Well it depends actually it doesn't always create a neutral solution. Here's the order: Strong Alkali + Strong Acid = Neutralisation (water + salt) Strong Alkali + Weak Acid = Weak Alkali Weak Alkali + Weak Acid = Neutralisation ( water + salt) Weak Alkali + Strong Acid = Weak Acid Strong Alkali + Strong Acid = Neutralisation (water + salt) Hope it helps! :)
BaNO32 This is strong electrolyte weak electrolyte or nonelectrolyte?
it is a strong electrolyte because it occurs in strong bases and that's why it is bonded between two different elments
What would happen to the pH value if you mix equal amounts of a strong acid with a strong base?
The pH value will be reduced to nearly 1 with the effect of neutralisation and the end products of salt and water.
WHAT HAPPENS WHEN ACIDS AND AND BASES ARE MIXED TOGETHER?
When they are mixed together, a chemical reaction occurs. This chemical reaction is called neutralisation reaction. It is called so because they both neutralise each other to produce a salt and water. Also remember the following points.When a strong acid and weak base are mixed, the salt formed is an acidic salt.When a strong base and weak acid are mixed, the salt formed is a basic salt.When both the acid and base are strong, then the salt formed is a neutral salt .
Is salt an acid?
It depends you can sometimes get an alkaline salt.if you use a strong acid and a weak base during neutralisation you will get an acidic salt (eg. Ammonia chloride. Made from hydrochloric acid and ammonia) However, if you use a weak acid and a strong base during neutralisation you will get an alkaline salt (eg. Sodium ethanoate. Made from sodium hydroxide and ethanoic acid)
Is it always a case that a neutralisation of an acid by a base gives a neutral salt?
no if the acid is strong and the base is weak then the salt will be slightly acidic. sources: chemistry teacher :)
When a high system and low pressure system meet what usually occurs?
Strong winds occur in the area between the two systems.
How is neutralisation used to treat indegestion?
Stomach acid is hydrocloric acid. This has a pH scale of 1. This is tackled by a strong alkali to make the pH 7. aka neutral
Is sodium hydroxide and hydrochloric acid a neutralisation reaction?
Yes, it is. Sodium hydroxide and hydrochloric acid are both strong base and strong acid. It means that they dissociate fully in water. In neutralisation reaction the products of the reaction are: water, and salt of the two compounds. NaOH + HCl -> NaCl + H2O No H3O+ and OH- ions are formed, therefore solution after the reaction is neutral. There is but one condition, the reactants must be mixed stoichiometrically.
When is fluorescence strong?
Flluorescence is strong in systems in which emission occurs from the state with the lowest energy.
Which of the following is titrated using strong bases?
Titration is the controlled neutralisation of an acid and a base. If the titration is done using a weak acid and a strong base, it can be analysed in detail and all concentrations of the aqueous species at any volume addition of the titrant can be determined.
