Weak alkali can react with reducing sugars through a process known as caramelization. This reaction leads to the formation of brown compounds and a change in taste, color, and aroma of the sugar solution. The extent of this reaction depends on factors such as concentration of the alkali, temperature, and duration of the reaction.
What else can I help you with?
Differentiate the action of a strong base from a weak base from a weak base on a reducing sugar?
A strong base would rapidly denature a reducing sugar through a nucleophilic attack on the carbonyl group, leading to a quick breakdown of the sugar molecule. In contrast, a weak base would have a slower and less efficient reaction with the reducing sugar, resulting in a milder effect on the sugar molecule.
Is ammonia a strong alkali?
Yes, ammonia is a weak alkali. It is a weak base that can accept a proton to form the ammonium ion.
What pH is a weak alkali?
any concerted alkali is weak alkali
What pH would a weak alkali have?
A weak alkali would have a pH greater than 7 but less than 10. Examples of weak alkalis include ammonia and baking soda.
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.

Is limewater alkali or acid?
weak alkali.
What is the reaction when you add acids and alkali's?
you create a neutral solution -------------------------------------------------------------------------------------------- Well it depends actually it doesn't always create a neutral solution. Here's the order: Strong Alkali + Strong Acid = Neutralisation (water + salt) Strong Alkali + Weak Acid = Weak Alkali Weak Alkali + Weak Acid = Neutralisation ( water + salt) Weak Alkali + Strong Acid = Weak Acid Strong Alkali + Strong Acid = Neutralisation (water + salt) Hope it helps! :)
What pH is a weak alkali?
any concerted alkali is weak alkali
Is honey a reducing sugar or non reducing?
yes because honey is a monosaccharide All monosaccharides reduce weak oxidizing agents such as Cu2+ in fehlings's reagent.
Why does bicarbonate of soda have alkali?
NaHCO3 contain sodium - an alkali metal.
Is bicarbonate of soda a weak alkali?
Yes. It is a weak base.
What colour will universal indicator turn when mixed with a weak alkali?
Universal indicator will turn purple or blue when mixed with a weak alkali.
Is alkali an acid?
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
Is KOH a weak or a strong alkali?
Strong
What pH would a weak alkali have?
A weak alkali would have a pH greater than 7 but less than 10. Examples of weak alkalis include ammonia and baking soda.
