the acid turns the universal indicator to red while the sodium / calcium hydroxide which is alkali turns the universal indicator to purple .

The blue limus paper turned red when acid is added and red limus paper turned blue when alkali is added]]> 2021-02-02 02:58:44 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151666952 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151666961 chemical reaction]]> 2021-02-02 02:58:45 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151666961 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667225 grp 8
Chemical reaction changes the colour of the litmus paper from blue to red,red to blue]]> 2021-02-02 02:58:55 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667225 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667573 Grp2: Acid has a characteristic to change objects to red as it has more corrosion than Akali, which turns objects to blue

grp 2: Chemical reactions that causes the change of the litmus paper's colour]]> 2021-02-02 02:59:09 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667573 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667785 A chemical reaction totally not magic]]> 2021-02-02 02:59:16 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667785 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667837 I see that acid and alkaline have different effects on blue and red litmus paper.
I see that different acids have a different effect during the universal indicator the acids will have an orange/red/yellow colour, the alkaline however will have a green/blue/purple colour]]> 2021-02-02 02:59:19 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151667837 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151668200 i can conclude that there is chemical reaction in this experiment]]> 2021-02-02 02:59:35 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151668200 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151668270 grp 8

The acid had a chemical reaction with the blue limus paper and turned it red and the alkali had a chemical reaction with the red limus paper and turned it blue]]> 2021-02-02 03:00:12 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151669156 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151669446 chemical reaction when alkali and acid when there it is in contact with the litmus paper . ]]> 2021-02-02 03:00:23 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151669446 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151671299 Acid causes a chemical reaction in the blue litmus paper turning it red
Alkali causes a chemical reaction in the red litmus paper turning it blue]]> 2021-02-02 03:01:41 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151671299 https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151672595 Red litmus paper stands for acids, Blue litmus paper stands for alkali
How does the Universal Indicator indicate how acidic/mucb alkaline something is - Is it a chemical change or a physical change?]]> 2021-02-02 03:02:35 UTC https://padlet.com/xmspadlet/id8zb0ku2k6sso6c/wish/1151672595
