Indicators did not play any role to catalyse a reaction. Which of the following is true about nucleic acids. Gain of a proton by an acid forms its conjugate base.

It changes the color of the litmus paper to red. A Acid base titration done in the presence of indicators just to find out equivalence or end point of reaction. The truth about acids is- A Most acids are sour.

Acids are sour in taste. Acids give food a bitter taste due to the presence of hydroxonium ion and when it is dissolved in water to form an acidic solution it most times can conduct electricity ie tetraoxosulfate solution. Phenolphthalein turns colorless in acidic solutions.

Acids give food a bitter taste due to the presence of hydroxonium ion and when it is dissolved in water to form an acidic solution it most times can conduct electricity ie tetraoxosulfate solution. Nucleic acids always consist of a five-carbon sugar a nitrogenous base and one or more phosphate groups. These are the only ones I can remember atm but as you can see they both contain Hydrogen.

The correct options is B Aqueous solutions of acids conduct electricity. Some examples of acids are HCl and H2SO4. Which of these statements is not true regarding amino acids.

Strong acids produce solutions with a higher pH than weak acids. B Amino acids are dipolar ions or zwitterions. There are 11 essential amino acids.

All of the above. D stored as amino acids in muscle. Loss of a proton from a base forms its.

Which of the following statements about Brønsted-Lowry acids and bases is true. The answer is C which is why we measure things on a pH scale. A The amino group is ionizable.

What kind of ions are produced when an acid is dissolved in water and when a base is dissolved in water. Strong acids are very concentrated acids. C-5 of the pentose is joined to a phosphate group and C-1 to a nitrogenous base.

The conjugate base of a strong acid is itself a strong base. C All amino acids except glycine contain side chains. C The stronger the acid the larger the pKa.

All acids have H atoms bonded to electronegative oxygen atoms. B The stronger the acid the smaller the Ka. Which one of the following is true of the pentoses found in nucleic acids.

It is used to determine whether a solution is acidic or basic. Bitter by taste and change red litmus to blue. B The acidic group is ionizable.

The natural colour of the litmus is purple. Alkalis Base turn universal indicators into blue. Litmus paper is used as one of the chemical indicators.

Acidic solutions are sour in taste and strong acids have pH less than 7 which have the property of turning blue litmus paper to red. Sour by taste and change red litmus to blue. Which of the following statements is true for acids.

Nonessential amino acids are not needed to make proteins and thus serve little purpose in the body. Essential amino acids are produced by the body. Hydrochloric acid HCl and sulphuric acid solution ar ethe example of acidic solution.

Log in for more information. Changing one amino acid may or may not affect protein function. They are difficult to stain because of the outer layer of lipopolysaccharide in their cell wall D.
