What is the chemical name of an antioxidant?
There are many chemicals that can act as antioxidants, but one common example is ascorbic acid, which is also known as Vitamin C.
Can an amphoteric compound act like an acid and a base?
Am amphoteric substance can react as a base but also as an acid.
Which substance can act like an acid in aqueous solution?
HI
What can act like and acid and bases?
These substances are called amphoteric.
Why can a carboxyl act as an acid?
The carboxyl group loses a H ion and its negatively chaged, having a behave like an acid.
Is tin dioxide SnO2 an alloy?
SnO2, Tin Dioxide, is not an alloy. It is, however, the main ore of Tin (traditionally called as cassiterite). Tin Dioxide can be hydrated to yield "stannic hydroxide" or "stannic acid" since tin is amphoteric (ie., can act as base or acide). Alloys are solid solutions of metals (and not usually their oxides or other compounds).
Why is it that apple slices can be kept from browning by brushing them with lemon juice. infer what role lemon juice plays in this case?
Ascorbic acid from lemon juice act as a preservative; the reaction between polyphenol oxidase (an enzyme) with oxygen from air is stopped.
What does hydrchloric acid do?
Hydrochloric acid can act as a Bronsted acid, an oxidizing agent and as a reducing agent.
What does neutalize mean?
neutralisation means nullifying the effect of one substance by another like in acid base reactions acid+base-salt(neutral)
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.

How can a base act like water?
Because water is amphoteric and acts like a Bronsted-Lowry base when mixed with an acid, it will gain a proton and produce hydronium. This is just as a base gains a proton and forms a conjugate acid.
What are in the juices of a potato that makes it act like a battery?
The chemical in the potato that produces this electro-chemical reaction is phosphoric acid.
