Answer 2

$\bf\huge{Answer :}$

Acids :

• Acids change blue litmus paper into red litmus paper.
• They are usually sour.
• They're electrolytes.
• When they react which bases then they form salt and water.
• They give $\bf{H^+}$ ions in hydrogen.
• Example - Citric Acid, Oxalic acid, Lactic acid, etc.

Bases :

• Bases change red litmus paper into blue litmus paper.
• Bases are usually bitter.
• They're soapy to touch.
• They also conduct electricity in an aqueous solution.
• When they react which acids, then they form salt and water.
• They give OH- ions in water.
• Example: sodium hydroxide, potassium hydroxide, ammonium hydroxide, etc

Ph Scale :

• The alphabet 'P' in pH stands for potenz which means power in germen and the alphabet 'H' means hydrogen ion concentration.

• The pH scale is a scale used to check the strength of acid and base.

• It consists of 0-14 units which shows the strength.

Conditions :

1. If pH > 7, then the solution is basic.
2. If pH < 7, then the solution is acidic.
3. If pH = 7, then the solution is neutral.
