The Lissé and Lime were luxury variants of the XL and GL models respectively, marketed heavily towards women in Japan. [8] They featured an automatic transmission (with the option for a factory manual) and power steering as standard, and had unique upholstery in the interior. The Lissé is a 2-door Trueno, and the Lime is a 2-door Levin.
The Toyota Sprinter Trueno (トヨタ・スプリンタートレノ, Toyota Supurintā Toreno) is a series of compact sports coupés and liftbacks which were produced by Toyota from 1972 to 2000. The name trueno in Spanish means thunder. [1] In Japan, the Sprinter Trueno was exclusive to Toyota Auto Store locations. Its twin, the Toyota Corolla ...
pH indicators: a graphic view. A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1] Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O ...
The AE86 was available with a naturally aspirated 4A-GE 1,587 cc (1.6 L; 96.8 cu in) inline-four engine, a DOHC four-valve-per-cylinder motor, in Japan and Europe, which was also used in the first-generation MR2 G Limited (AW11), Corona GT (AT141), Celica 1600GT-R (AA63) and Carina 1600GTR (AA63) (Japan only) with a compression ratio of 9.4:1.
A roll of universal indicator paper Colors of universal indicator. A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a ...
Indicator: A substance that changes color in response to a chemical change. An acid–base indicator (e.g., phenolphthalein) changes color depending on the pH. Redox indicators are also used. A drop of indicator solution is added to the titration at the beginning; the endpoint has been reached when the color changes.
A pH indicator is a weak acid or weak base that changes colour in the transition pH range, which is approximately pK a ± 1. The design of a universal indicator requires a mixture of indicators whose adjacent pK a values differ by about two, so that their transition pH ranges just overlap.
Because it changes color at the pK a of a mid strength acid, it is usually used in titration of strong acids in weak bases that reach the equivalence point at a pH of 3.1-4.4. [3] Unlike a universal indicator , methyl orange does not have a full spectrum of color change, but it has a sharp end point.
