Malic acid is agt what form at 100 degrees Celsius?
At 100 degrees C, malic acid is still a solid. At 130 degrees C, malic acid will decompose and form carbon monoxide and carbon dioxide gases.
What elements are found in malic acid?
These elements are C, H, O.
What acid does an apple contain?
The main acid in apples and other fruits and vegetables is malic acid, which creates the tartness of green apples and certain varieties. It is found in our cells as one of the chemicals in the process of breaking down sugar to provide energy for our cells. Apples also contain ascorbic acid (vitamin C) and small amounts of vitamin B5 (also an acid).
What is the name of the acid in lemons?
Citric acid (which is responsible for the sour taste) and ascorbic acid (which most of us know as vitamin C).
Is there such thing as an acidic solid?
There are many organic acids that are soluble though solid crystals:citric acid (Mp. 153 °C),tartaric acid (three Mp.: 171-174 °C (L-tartaric), 206 °C (DL, racemic), 146-148 °C (meso))malic acid (Mp. 130 °C),lactic (two different Mp.: L-lactic acid 53 °C, D: 53 °C and D/L, racemic: 16.8 °C).
What type of acid does tomato sauce contain?
Tomato acid is mostly Citric acid and Malic acid at a 1 to 0.6 ratio respectively in the ripe red fruit. In the green fruit the ratio is 1 to 1.3. Therefore the acid in Tomato sauce contributed by the Tomatoes is Citric acid and Malic acid. Tomato sauce may however have other acidic ingredients that substantially contribute to its finished acidity. All Vinegars are principally Acetic acid. Some may also contain smaller amounts of other acids from their original ingredients. For example Tartaric acid from Grapes in Wine vinegars and Malic acid in Apple vinegars. Lemon & Lime juice contribute Citric acid. Wine contributes mostly Tartaric acid. Tamarind contributes mostly Tartaric acid. Sour Milk, Cream and Yoghurts contribute Lactic acid. Acids can also be added during food processing to act as acidity regulators. These may be listed by reference (E) numbers; the most common of which are which are as follows: E260 - Acetic acid E270 - Lactic acid E296 - Malic acid E300 - Ascorbic acid (Vitamin C) E330 - Citric acid E334 - Tartaric acid There are also many more acids and acidity regulators used in food processing, all of which can be found via their E numbers, although most likely not in the amounts or as commonly as those listed above in Tomato sauce.

Is a lemon acid?
The correct answer to your question is: No, lemon is NOT acid. However, a lemon is very acidic with a pH of 2.3 or thereabouts. Lemon juice contains Citric Acid and smaller amounts of other organic acids such as Ascorbic Acid (vitamin C) and Malic Acid.
