Properties of Acids & Bases
All soluble bases - also known as Alkalis - release this compound when dissolved in water.
What is the hydroxide ion OH-?
The two equations that are used to represent the pH scale in terms of base 10.
What is pH = -log10[H+] and [H+] = 10-pH?
A theory focusing on the transferring of H+ ions during an acid-base reaction. Acids donate H+ and Bases accept H+.
What is the Bronsted-Lowry theory?
The balancing values of this chemical equation: __HCl (aq) + __CaCO3 (s) ↔ __CaCl2 (aq) + __H2O (l) + __CO2 (g)
What is 2, 1, 1, 1, 1?
The color that an acid changes a blue litmus dye to when testing an acid.
what is red?
A lab technique that's purpose is to reach an equivalence point meaning the amount of an acid and a base is neutral. It is used to determine the unknown concentration of either an acid or a base, to determine this, an indicator must be used.
What is an acid-base titration?
The scale pH goes by that demonstrates an increase or decrease in H+ ions and can determine an acid or a base based on the change of those H+ ions by a factor of ten.
What is the 1-14 scale?
The piece that must be present for an acid-base reaction to occur and allows the reaction to occur both ways and differ by one hydrogen ion/proton.
What are conjugate acid-base pairs?
Two possible parent acids and bases capable of producing common table salt NaCl as one of the products in a reaction.
What is HCl and NaOH?
What elements or species are called when they do not change in a reaction and can furthermore be ignored in the reaction.
The net ionic equations of both a Neutralization reaction and acid + carbonate reactions.
What is H+ (aq) + OH- (aq) ↔ H2O (l) for neutralization and 2H+ (aq) + CO32- (aq) ↔ H2O (l) + CO2 (g) for acid + carbonate reactions?
An alternative to pH paper or indicator that provides more accurate readings with a probe that detects the concentration of H+ ions and must be calibrated with a buffer solution and standardized temperature to provide such accurate readings.
What is a pH meter?
Identify the conjugate pair of these acids and bases: H2CO3 (acid) and NO2- (base).
What is HCO3- (conjugate base) and HNO2 (conjugate acid)?
The best indicator to use in a titration experiment calculating the concentration of ethanoic acid in vinegar titrated with standard solution sodium hydroxide.
What is Phenolphthalein indicator?
An indicator that is formed by mixing several indicators together and changes to a lot of different colors depending on the different acids or alkalis. It can be used to measure the concentration of H+ on the pH scale.
What is a Universal Indicator?
The type of reaction between acids and bases that releases heat and forms one mole of water and is approximately similar to the heat change of Delta H = -57 kJ mol-1.
What are Neutralization reactions?
The different pH values that distinguish an acid from a base or a neutral compound.
What is 1-6 as an acid scale, 8-14 as a base scale, and 7 as a neutral scale for pH of an acid, base or neutral compound?
The conjugate pairs of this reaction: CH3COOH (aq) + H2O (l) ↔ CH3COO- (aq) + H3O+ (aq)
What are CH3COOH & CH3COO- and H2O & H3O+ as conjugate acid-base pairs?
The best indicator to use in a titration to find the concentration of sodium hydroxide titrated with standard solution hydrochloric acid.
What is methyl orange indicator?
Famous French scientist Lavoisier proposed a theory that acids were made by this newly discovered element that means "Acid Former" by a compound of this element and a non-metal.
What is Oxygen?
These are the three types of reactions in which acid reacts to form a salt.
What are:
1.) Acid + Metal ↔ Salt + Hydrogen
2.) Acid + Base ↔ Salt + Water
3.) Acid + Carbonate ↔ Salt + Water + Carbon Dioxide
What Kw represents in the equation Kw = [H+][OH-] and its temperature value.
What is the ionic product constant of water and at standard temperature of 298 K equals 1.00 x 10-14?
These elements are called this when they are able to dissociate and release H+ as an acid, and must be able to accept H+ as a base for they have a lone pair of electrons. Shortly, this element must possess a lone pair of electrons and a hydrogen atom that can be released as an ion.
What is an amphiprotic element?
the pH of sample of water that is tested to have [H+] = 3.2 x 10-5 mol dm-3 at 298 K temperatures.
What is 4.49?
The Bronsted-Lowry Acid and the Bronsted-Lowry Base in this reaction: NH4+ + NO2- ↔ HNO2 + NH3
What is NH4+ as a Bronsted-Lowry Acid and NO2- as a Bronsted-Lowry Base?
