2 examples of where acid is useful
That acid is said to be a weak acid. Examples of strong acids are hydrochloric acid (HCl), sulfuric acid (H 2 SO 4), and nitric acid (HNO 3). Among the best-known strong bases are sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (CaOH 2). Acids & bases. Vocabulary acid anthocyanin base chemical change indicator pH In theory, any substance that undergoes a reversible chemical change when pH changes can be used as an acid-base indicator. In practice, a sharp change in some easily detectable property of the substance is required. Vinegar, for example, is a water solution of acetic acid that has been used for centuries. The first modern definitions for acids and bases were suggested by Swedish chemist Svante Arrhenius (1859–1927). Arrhenius proposed that acids be defined as chemicals that produce positively charged hydrogen ions, H + , in water. Vinegar, for example, is a water solution of acetic acid that has been used for centuries. The first modern definitions for acids and bases were suggested by Swedish chemist Svante Arrhenius (1859–1927). Acids and bases have been known since prehistoric times. Vinegar, for example, is a water solution of acetic acid that has been used for centuries. Sulfuric acid is the most abundant product of the chemical industry. It is used in the refining of metals and in the manufacture of a wide variety of substances. It is used for the pickling of steel to retard corrosion, in the refinement of petroleum, and in the manufacture of fertilizers. Vocabulary acid anthocyanin base chemical change indicator pH In theory, any substance that undergoes a reversible chemical change when pH changes can be used as an acid-base indicator. In practice, a sharp change in some easily detectable property of the substance is required. A special property of acids and bases is their ability to neutralize the other's properties. In an acid-base (or neutralization) reaction, the H + ions from the acid and the OH-ions from the base react to create water (H 2 O). Another product of a neutralization reaction is an ionic compound called a salt. An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic. An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution.
