Solution and Explanation
Step 1: निरीक्षण समजून घेणे.
तांब्याच्या भांड्यांवर हवेशी संपर्क आल्याने हिरवट थर तयार होतो. हा थर Copper Carbonate (CuCO$_3$) आणि Copper Hydroxide (Cu(OH)$_2$) पासून बनलेला असतो.
Step 2: आम्लाची क्रिया.
लिंबू आणि चिंच या पदार्थांमध्ये सिट्रिक आम्ल (Citric Acid) असते. हे आम्ल तांब्याच्या पृष्ठभागावर तयार झालेल्या कार्बोनेट थराशी अभिक्रिया करून तो थर विरघळवते.
Step 3: निष्कर्ष.
म्हणून तांब्याची भांडी स्वच्छ करण्यासाठी लिंबू किंवा चिंच वापरतात कारण त्यांतील आम्ल तांब्यावरील हिरवट थर काढून टाकते.
