An acid can be described as "strong" or "dilute" based on different factors. The strength of an acid refers to the extent to which it dissociates in water, with a strong acid being one that dissociates almost completely. On the other hand, an acid is considered dilute based on its concentration in solution, which refers to how much acid is dissolved in water.

A strong but dilute acid is one that dissociates nearly completely but has a low concentration. For example, a 0.01 mol/dm³ sulfuric acid solution is strong due to its complete dissociation but dilute because of its relatively low concentration.

Alkali metals belong to Group 1 of the periodic table, which means they have a single electron in their outermost shell. To achieve a stable noble gas configuration, these elements seek to lose this electron. Since it requires very little energy to remove this lone electron, alkali metals react vigorously with other substances in an attempt to achieve a more stable electron configuration.

A Bronsted-Lowry acid is defined as a proton donor. In aqueous solution, it can dissociate by releasing a hydrogen ion (H+), which is essentially a proton. This process results in the formation of a negatively charged anion as the proton is donated.

Cracking is a chemical process in which large hydrocarbon molecules are broken down into smaller, more useful molecules, typically using a catalyst. This process results in the formation of alkanes and alkenes.

Alkanes are hydrocarbons that contain only single bonds between carbon atoms.

Alkenes, on the other hand, contain at least one double bond between carbon atoms, with the remaining bonds being single bonds.

Cracking is commonly used in the petroleum industry to produce shorter-chain hydrocarbons that are in higher demand, such as gasoline and diesel.

A substance that facilitates a chemical reaction by offering an alternative pathway, which requires less energy than the reaction's activation energy.
