Explanation:

1.Acetic acid and citric acid

2.Hydrochloric acid (HCL),Nitric acid(HNO3).

3.Sodium Hydroxide (NaOH),Sodium Hydrogencarbonate(NaHCO3).

4.Red Cabbage Leaves, Turmeric

5.HCL+NaHCO3=NaCl+H2O

6.Acidic

7.Phenolpyhalene

8.H2O, Aqueous solution of NaCl

Answer 2

1) two organic acid

• formic acid (methanoic acid) HCOOH
• formic acid (methanoic acid) HCOOHAcetic acid (ethanoic acid)CH3COOH
• formic acid (methanoic acid) HCOOHAcetic acid (ethanoic acid)CH3COOHpropionic acid(propanoic acid) CH3CH2CH2COOH

2)

• Nitric acid: HNO
• Nitric acid: HNOPhosphoric acid: H3PO.
• Nitric acid: HNOPhosphoric acid: H3PO. Sulfuric acid: H2SO.
• Nitric acid: HNOPhosphoric acid: H3PO. Sulfuric acid: H2SO. Perchloric acid: HClO.

3)

• NaOH sodium hydroxide
• NaOH sodium hydroxideCa(OH)2 calcium hydroxide

4)

• natural Indicator is a type of indicator that can be found naturally and can determine whether the substance is an acidic substance or a basic substance.

5)

• HCl + NaOH (gives) NaCl+H2O

HCl + NaOH (gives) NaCl+H2O(acid) (base). (salt). (water)

6)

• Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly.

7)

synthetic

• syntheticphenolphthalein
• syntheticphenolphthaleinmethyl orange

8)

Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often adsorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity..

9)

alkaline solutions

• Phenolphthalein is naturally colorless but turns pink in alkaline solutions

10)

• Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often adsorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity.
